## Abstract

A manufacturing method of an actuator having a support body, a movable body, a viscoelastic member adhesively bonded to one side member of the support body and the movable body by a first adhesive layer, and a magnetic drive circuit structured to relatively move the movable body may include, for adhesively bonding the viscoelastic member to the one side member by the first adhesive layer, a first step in which the viscoelastic member is disposed on a side of one face of a first jig, a second step in which the viscoelastic member and the one side member are overlapped with each other through an adhesive, a third step in which the adhesive is hardened to adhesively bond the one side member and the viscoelastic member to each other by the first adhesive layer, and a fourth step in which the first jig is separated from the viscoelastic member.

## Claims

### Claim 1

A manufacturing method of an actuator, wherein the actuator comprises:
a support body;
a movable body, which is movable with respect to the support body;
a viscoelastic member, which is adhesively bonded to one side member of a member structuring the support body and a member structuring the movable body by a first adhesive layer; and
a magnetic drive circuit, structured to relatively move the movable body with respect to the support body;
the manufacturing method comprising steps for adhesively bonding the viscoelastic member to the one side member by the first adhesive layer, wherein the steps comprises:
a first step, in which the viscoelastic member is disposed on a side of one face of a first jig;
a second step, in which the viscoelastic member and the one side member are overlapped with each other through an adhesive;
a third step, in which the adhesive is hardened to adhesively bond the one side member and the viscoelastic member to each other by the first adhesive layer; and
a fourth step, in which the first jig is separated from the viscoelastic member.

### Claim 2 (depends on 1)

The manufacturing method of an actuator according to claim 1, wherein
previously disposing the one side member on one face of a second jig, and
in the second step, the first jig and the second jig are overlapped with each other, so that the viscoelastic member and the one side member are overlapped with each other through the adhesive.

### Claim 3 (depends on 2)

The manufacturing method of an actuator according to claim 2, wherein
previously disposing a plurality of the viscoelastic members on the one face of the first jig,
previously disposing a plurality of the one side members on the one face of the second jig, and
in the second step, the first jig and the second jig are overlapped with each other, so that the plurality of the viscoelastic members and the plurality of the one side members are respectively overlapped with each other through the adhesive.

### Claim 4 (depends on 3)

The manufacturing method of an actuator according to claim 3, wherein
in the second step, the one face of the second jig is set to face upward and the one face of the first jig is set to face downward, and the first jig and the second jig are overlapped with each other.

### Claim 5 (depends on 1)

The manufacturing method of an actuator according to claim 1, wherein
in the first step, a conveyance head disposes the viscoelastic member on the one face of the first jig, and
after that, and before the second step, the conveyance head is separated from the viscoelastic member.

### Claim 6 (depends on 5)

The manufacturing method of an actuator according to claim 5, wherein the conveyance head comprises:
a suction part, structured to vacuum-suck the viscoelastic member; and
a bar-shaped member, movable between an upper side position where the bar-shaped member is retreated to an upper side with respect to the suction part and a lower side position where the bar-shaped member is protruded to a lower side with respect to the suction part, and
when the conveyance head is to be separated from the viscoelastic member, the bar-shaped member is protruded to the lower side from the suction part.

### Claim 7 (depends on 1)

The manufacturing method of an actuator according to claim 1, wherein
the viscoelastic member is a gel-state member.

### Claim 8 (depends on 1)

The manufacturing method of an actuator according to claim 1, wherein
after the fourth step, an other side member of the member structuring the support body and the member structuring the movable body and the viscoelastic member are adhesively bonded to each other by a second adhesive layer.

### Claim 9 (depends on 4)

The manufacturing method of an actuator according to claim 4, wherein
in the first step, a conveyance head disposes the viscoelastic member on the one face of the first jig, and
after that, and before the second step, the conveyance head is separated from the viscoelastic member.

### Claim 10 (depends on 9)

The manufacturing method of an actuator according to claim 9, wherein the conveyance head comprises:
a suction part, structured to vacuum-suck the viscoelastic member; and
a bar-shaped member, movable between an upper side position where the bar-shaped member is retreated to an upper side with respect to the suction part and a lower side position where the bar-shaped member is protruded to a lower side with respect to the suction part, and
when the conveyance head is to be separated from the viscoelastic member, the bar-shaped member is protruded to the lower side from the suction part.

### Claim 11 (depends on 10)
