Abstract

The invention provides a novel method for producing a composite member by fixing a surface member to the outer peripheral surface of a core member. A method for producing a composite member having a core member and a surface member fixed to the outer peripheral surface of the core member includes the surface member providing step of providing the surface member having magnetism lower than magnetism of the core member made of a conductive material on the outer peripheral surface of the core member, and the fusing step of electromagnetic induction heating the core member from outside the surface member to melt at least one of facing regions between the surface member and the core member with heat of the heated core member and fuse the surface member to the core member.
