## Abstract

There is provided a composite structure including: at least two substrates which are made of thermoplastic resin and which are bonded by thermocompression; and at least one member which is made of a material whose heat distortion temperature is higher than a heat distortion temperature of the thermoplastic resin and which is inserted into a space formed in at least one of the substrates. The member inserted in the space is fixed and held by wall surfaces which form the space of the substrates and which are thermally deformed by thermocompression.

## Claims

### Claim 1

A composite structure comprising:
at least two substrates which are made of thermoplastic resin and which are bonded by thermocompression; and
at least one member which is made of a material whose heat distortion temperature is higher than a heat distortion temperature of the thermoplastic resin and which is inserted into a space formed in at least one of the substrates,
wherein the member inserted in the space is fixed and held by wall surfaces which form the space of the substrates and which are thermally deformed by thermocompression.

### Claim 2 (depends on 1)

The composite structure according to claim 1, wherein
a position of the member in the space is determined by the wall surfaces.

### Claim 3 (depends on 2)

The composite structure according to claim 2, wherein
the member is positioned in the space such that regions that are respectively formed in at least one of the substrates and in the member are linked.

### Claim 4 (depends on 3)

The composite structure according to claim 3, wherein
the composite structure is a microchip including a flow path which is formed as the regions and through which liquid passes.

### Claim 5 (depends on 4)

The composite structure according to claim 4, further comprising:
a light irradiated portion where light is irradiated onto one of the quid that flows through the flow path and a sample contained in the liquid,
wherein the light irradiated portion is formed by the member made of a material having optical transparency that is superior to that of the thermoplastic resin that forms the substrates.

### Claim 6

A manufacturing method for a composite structure, comprising:
arranging at least two substrates which are made of thermoplastic resin and which have a space that is formed in at least one of the substrates;
inserting, into the space, at least one member that is made of a material whose heat distortion temperature is higher than a heat distortion temperature of the thermoplastic resin; and
bonding the substrates by thermocompression and thereby causing wall surfaces, which form the space of the substrates and which are thermally deformed, to fix and hold the member inserted in the space.

### Claim 7 (depends on 6)

The manufacturing method according to claim 6, wherein
in the step of causing the wall surfaces to fix and hold the member, a position of the member in the space is determined by the wall surfaces.

### Claim 8 (depends on 7)

The manufacturing method according to claim 7, wherein
in the step of causing the wall surfaces to fix and hold the member, the member is positioned in the space such that regions that are respectively formed in at least one of the substrates and in the member are linked.

### Claim 9 (depends on 8)

The manufacturing method according to claim 8, wherein
in the step of causing the wall surfaces to fix and hold the member,the thermocompression of the substrates is performed at a temperature which is higher than the heat distortion temperature of the thermoplastic resin that forms the substrates and which is lower than the heat distortion temperature of the material that forms the member.
