Provided is a composite body in which a resin and a metal are contact-bonded with excellent adhesive force. Also provided is a composite body which is suppressed in decrease of bonding strength between a resin and a metal due to water absorption of the resin even if the composite body is left in rain or water, or is left in a high humidity environment or the like for a long period of time. The present invention relates to a composite body which is obtained by contact-bonding a thermoplastic resin (A) and a metal (B), and which is characterized in that the thermoplastic resin (A) is a polyamide elastomer (1A) or a thermoplastic resin composition (2A) that contains a water absorbent thermoplastic resin (2a) and a metal hydroxide (2b).

Composite body of metal and thermoplastic resin

A corrugated polyamide tube composed of a corrugated outer tube layer of polyamide resin and a flat inner tube layer fixed to the outer tube layer at bottom portions thereof, in which the inner tube layer is made essentially of a polyetheramide elastomer.

Corrugated polyamide tube

A thermoplastic resin composition composed of a thermoplastic resin and a polyamide elastomer in which the polyamide elastomer contains at least 50 weight % of a polyetheramide elastomer prepared by polymerization of a tri-block polyetherdiamine compound, a polyamide-forming monomer is an aminocarboxylic acid and/or a lactam compound, and a dicarboxylic acid compound, in which the tri-block polyetherdiamine compound has the formula (1):[each of x and y is an integer of 1 to 20, and y is an integer of 4 to 50].
