## Abstract

A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X of forming a member a provided with a perforation for constituting said action chamber, a step Y of adjoining an end aperture of said perforation to another member b constituting an intermediate supply chamber of said liquid, and a step Z of attaching to said member c another member c for forming a slit in the vicinity of the other end aperture of said perforation.

## Claims

### Claim 1

A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X' for forming a member a' having a perforation for constituting said action chamber by forming a curable resin layer on a surface of a first sub-member, forming a groove on said surface bearing said resin layer and curing said resin layer while said surface bearing said resin layer is maintained in contact with a second sub-member thereby adjoining said sub-members, a step Y' of adjoining an end aperture of said perforation to another member b' constituting an intermediate supply chamber of said liquid, and a step Z' of attaching to member a' another member c' for forming an opening in the vicinity of the other end aperture of said perforation.

### Claim 2 (depends on 1)

A method according to the claim 1, wherein each of said sub-members is plate-shaped member.

### Claim 3 (depends on 1)

A method according to the claim 1, wherein said step X' comprises forming plural perforations in a substantially parallel manner in said member a'.

### Claim 4 (depends on 3)

A method according to the claim 3, wherein each of said perforations is provided with a planar heating element.

### Claim 5 (depends on 1)

A method according to the claim 1, wherein planar heating elements are provided on the surface of said second sub-member in said step X'.

### Claim 6

A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X' for forming a member a' having a perforation for constituting said action chamber by forming a curable resin layer on a surface of a first sub-member, forming a groove on said surface bearing said resin layer and curing said resin layer while said surface bearing said resin layer is maintained in contact with a second sub-member thereby bonding said sub-members, a step Y' of adjoining an end aperture of said perforation to another member b' constituting an intermediate supply chamber of said liquid.

### Claim 7 (depends on 6)

A method according to the claim 6, wherein each of said sub-members is a plate-shaped member.

### Claim 8 (depends on 6)

A method according to the claim 6, wherein said step X' comprises forming plural perforations in a substantially parallel manner in said member a'.

### Claim 9 (depends on 8)

A method according to the claim 8, wherein each of said perforations is provided with a planar heating element.

### Claim 10 (depends on 6)

A method according to the claim 6, wherein planar heating elements are provided on the surface of said second sub-member in said step X'.

### Claim 11

A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X' of adjoining plural members with a curable resin to form a determined structure, forming a curable resin layer on at least one of said members, bringing said resin layer to an intermediate state of the curing reaction, forming grooves on a face of said member bearing said resin layer, and curing said resin layer while it is maintained in contact with the other member thereby achieving adhesion of said members, and a step Y of adjoining an end aperture of said grooves to another member constituting an intermediate supply chamber of said liquid.

### Claim 12

A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X' for forming a member a' having a perforation for constituting said action chamber and an intermediate supply chamber of said liquid by forming a curable resin layer on a surface of a first sub-member, forming a groove on said surface bearing said resin layer and curing said resin layer while said surface bearing said resin layer is maintained in contact with a second sub-member thereby bonding said sub-members.

### Claim 13 (depends on 12)

A method according to the claim 12, wherein each of said sub-members is a plate-shaped member.

### Claim 14 (depends on 12)

A method according to the claim 12, wherein said step X' comprises forming plural perforations in a substantially parallel manner in said member a'.

### Claim 15 (depends on 14)

A method according to the claim 14, wherein each of said perforations is provided with a planar heating element.

### Claim 16 (depends on 12)

A method according to the claim 12, wherein planar heating elements are provided on the surface of said second sub-member in said step X'.

### Claim 17

A method for producing a recording head for ejecting a recording liquid in an action chamber from an orifice connected with said action chamber in a state of small droplets and depositing at least a part of said droplets onto a recording surface to achieve recording, said method comprising a step X' of adjoining plural members with a curable resin to form a determined structure, forming a curable resin layer on at least one of said members, bringing said resin layer to an intermediate state of the curing reaction, forming grooves constituting said action chamber and an intermediate supply chamber of said liquid on a face of said member bearing said resin layer, and curing said resin layer while it is maintained in contact with the other member thereby achieving adhesion of said members.
