Since the brush tip 9, which has already been formed, is welded, sufficient dimensional accuracy cannot be obtained due to bending to the left or right or shifting back and forth, as shown in Figures 8 and 9. After the mounting of the spring base material 10, positional accuracy from the reference hole 11 to the brush contact point 12 could not be obtained, and therefore stable contact with the opposing substrate could not be ensured.
