A multilayered printed circuit board includes a first surface layer that includes a semiconductor integrated circuit, a second surface layer that includes a bypass capacitor and that is opposite to the first surface layer, a main power supply wiring layer, and a ground layer between the first and second surface layers. A cost-effective production of support arms in different sizes and shapes is obtained by cutting at least the accommodating arm from a steel panel blank and forming it into a hollow profile and providing it with at least one transverse reinforcement. For example, when a sliding contact is manufactured by blanking a metal sheet material, the tip portion of the finger 12a of the brush 12 of the sliding contact piece 10 which is obtained by blanking is irradiated with a laser beam, whereby the tip portion is heated and melted.
