Claim:
1. A microchip comprising: at least two substrates each comprising a thermoplastic resin and which are bonded by thermocompression; a first flow path formed in at least one of the substrates; a space provided in at least one of the substrates and which separates a first portion of the first flow path from a second portion of the first flow path; at least one member comprising a material whose heat distortion temperature is higher than a heat distortion temperature of the thermoplastic resin and which is provided in the space, the at least one member including at least one engagement end including a protrusion extending into a recess formed between the at least two substrates; a second flow path formed in the member; and a light irradiated portion where light is irradiated onto the microchip, wherein the member provided in the space is fixed and the protrusion is held within the recess by wall surfaces which form the recess and which are thermally deformed by thermocompression, wherein the member is in contact with at least a part of a surface of at least one of the substrates, wherein the light irradiated portion of the microchip corresponds to the member, and wherein the member is positioned in the space such that the first portion of the first flow path is linked to the second flow path at a first end of the member and the second portion of the first flow path is linked to the second flow path at a second end of the member.
