A lead wire implanting apparatus is provided that can fabricate high-quality brushes that are without variations in implanting height and implanting strength and free from cracks and that can make the reproducibility of set values better and improve the workability in setup changing. The lead wire implanting apparatus has a tamping member and a storing cup for storing conductive metal powder, for implanting and fixing a lead wire to a brush main body by performing a tamping action of the tamping member a predetermined number of times. The apparatus has a linear-type servo motor serving as a drive source for driving the tamping member in vertical directions, a first position detector for detecting a shift position of the tamping member, and a controller device for controlling the linear-type servo motor based on detected information by the first position detector to cause the tamping member to perform a predetermined tamping action.
