Abstract: Electric motor includes stator, rotor, a pair of bearings, outer-ring conducting part, and printed circuit board. Outer-ring conducting part electrically couples outer rings to each other that are included respectively in the pair of bearings. Printed circuit board includes drive circuit and an impedance element. Drive circuit includes ground line. Drive circuit controls an electric current that flows through stator winding. The impedance element is formed with at least not smaller than one pair of conductive patterns. One of the conductive patterns forming the impedance element is electrically coupled with outer-ring conducting part. The other of the conductive patterns forming the impedance element is electrically coupled with ground line included in drive circuit.

Abstract: A method for forming an electrical connection structure part according to the present invention includes a step of covering, with an alloy body, a connection part between a first conductor part and a second conductor part, so as to form the electrical connection structure part. The first conductor part contains aluminum. The second conductor part has a surface covered with an ingredient containing nickel. The alloy body contains tin, silver, and nickel. The method further includes steps of: connecting the first conductor part and the second conductor part to each other to form the connection part; melting the alloy body; and dipping at least the connection part into the molten alloy body.
