Abstract

A joining method for joining a resin member and a metal member by heating is provided. Joining of the resin member and metal member is performed by heating a joining interface of the resin member and metal member to a temperature in a range of equal to or higher than a decomposition temperature of the resin member and lower than a temperature at which gas bubbles are generated in the resin member and by cooling a surface of the resin member on the opposite side from a joining surface thereof with the metal member to a temperature that is lower than the melting point of the resin member.

First claim

The invention claimed is:

1. A joining system, comprising:
a resin;
a metal that includes at least one concavity that is formed in a zone of the metal around a joining region of the resin and the metal;
a heating tool configured to heat a joining interface of the resin and the metal from a top surface of the metal on an opposite side of the metal from a bottom joining surface of the metal in contact with the resin; and
a cooling tool configured to cool a surface of the resin on an opposite side of the resin from a joining surface thereof with the metal to a temperature that is lower than a melting point of the resin.

2. The joining system according to claim 1 , wherein the heating tool is configured to heat the joining interface of the resin and the metal to a temperature in a range of equal to or higher than a decomposition temperature of the resin and lower than a temperature at which gas bubbles are generated in the resin.

3. The joining system according to claim 1 , wherein each of the at least one concavity is a slit that penetrates through the metal and that is formed in a zone of the metal around a joining region of the resin and the metal.

4. The joining system according to claim 3 , wherein each of the at least one slit penetrates through the metal from the top surface of the metal to the bottom surface of the metal.
