2. Description of the Related Art A multi-wire bundle sliding brush has a wire diameter of several tens of μm.
A few to several tens of ultrafine wires are bundled on the same plane and attached and fixed to a base material by electric resistance welding. At this time, various efforts have been made to strongly stabilize the electric resistance welding strength. One of them is a method of providing a base material with a projection perpendicular to the longitudinal direction of the wire.

Conventionally, in the processing of projections, the upper and lower dies having a concave portion and the lower die having a convex portion are used for molding. At this time, it was attempted to obtain the parallelism with high accuracy by setting the projection end face in which the lengths of the concave portion and the convex portion are approximately the same length to be in a state close to shearing (refer to Japanese Patent Laid-Open No. 1-97385). However,
Depending on the size of the material, swelling and bending may occur due to uneven molding due to distortion, and the parallelism may not be sufficient, which causes weak welding strength of the multi-wire bundle and uneven tip parts. It was
