Abstract
A motor wiring member configured to supply three-phase alternating current to a motor includes conductive wires, each of which has a connecting portion being provided at one end and being configured to be connected to a coil end of a stator of the motor, a terminal being provided at an other end of each conductive wire and being configured to be connected to an electrode of a terminal block, and a surge suppression section being configured to suppress an overvoltage from being applied to the motor. The surge suppression section includes three series circuits, each of which includes a resistor and a capacitor. One ends of the three series circuits are electrically connected to the conductive wires of respective phases, and other ends of the three series circuits are electrically connected to each other. The surge suppression section is provided along with the conductor wires near the terminal and is located between the terminal and the connecting portion.
