Abstract
There is provided a method for producing a metal-resin composite including a metal member and a resin member which are joined together, the resin member containing at least a thermoplastic resin. The method includes a step of joining together the resin member and the metal member by melting the resin member with the frictional heat generated in the surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed. The melting point of the thermoplastic resin is 260° C. or more.

A metal-resin composite comprising a metal member and a resin member which are joined together,
- wherein the resin member contains at least a thermoplastic resin;
- the resin member and the metal member are joined together by melting the resin member with frictional heat generated in a surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed;
- the melting point of the thermoplastic resin is 260° C. or more;
- the melt viscosity of the resin member is 1000 to 5000 Pas;
- and
- wherein a retention rate of a joining strength of the metal-resin composite after a heat cycle test is 80% or more.
