To provide a method for producing a joining member in which a carbon fiber composite material containing a thermoplastic resin as a matrix and a metal are firmly joined. A method for producing a joining member obtained by joining a carbon fiber composite material containing a thermoplastic resin as a matrix and a metal, wherein the surface of the metal is treated with a solution containing a specific triazine thiol derivative. (I), a step (ii) of providing a thermoplastic resin layer having a thickness of 5 to 5 mm between the treated metal surface and the carbon fiber composite material, and heating and melting the thermoplastic resin layer to form a metal surface Then, a joining member is manufactured by the step (iii) of joining (melting) the carbon fiber composite material. |
