<p>A PCB(Printed Circuit Board) with a ground conductor for an electric motor and an electric motor are provided to implement a reliable contact with the ground conductor by forming a metal wiring on the outer terminal part of the PCB. A PCB with a ground conductor for an electric motor includes two main substrate planes(12,14), four outer terminal parts(16,18,20,22), electric devices(12), and a metal wiring(26). The metal wiring(26) is formed on one of the outer terminal parts(18). The metal wiring(26) is made of a material substance which has a high electrical conductivity. The metal wiring(26) is plated to prevent corrosion and makes electrical connection with the ground conductor on the PCB.</p> |
