PROBLEM TO BE SOLVED: To prevent damage of a cable connected between a power conversion unit and a control circuit board, and to prevent functional degradation of a circuit-board mounting chassis.SOLUTION: An electrical apparatus includes: a power conversion unit 1 including a plurality of switch elements 24 that convert DC power into AC power; a control circuit 14 controlling the operation of the plurality of switch elements 24; a metal plate member 16 interposed between the power conversion unit 1 and the control circuit 14, and including a portion configured so that an end portion protrudes toward the power conversion unit side; and a cable connecting the plurality of switch elements 24 and the control circuit 14 through the portion of the plate member. The plurality of switch elements 24 and the plate member 16 are commonly connected to a ground potential, thereby preventing damage of the cable. Moreover, the purposely notching of a mounting surface 16b to route the cable is not required, thereby preventing functional degradation of the circuit-board mounting chassis 16. |
