A wire member that exhibits an excellent sliding property is provided. A wire memberincludes: a core memberthat has an elongated shape; and a surface-disposed memberthat is spirally disposed on a surface of the core memberso as to leave predetermined spaces along a longitudinal direction of the core member. In a cross-sectional view taken along the axis of the core member, the front end and the rear end of each of projectionsA formed by the surface-disposed memberrespectively form contact angles &#x3b8;each being 5&#xb0; or greater relative to the surface of the core member

Wire member

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.
