PROBLEM TO BE SOLVED: To provide an electrical apparatus that hardly suffers an impact by noise emitted by a communication board.SOLUTION: An electrical apparatus 1 for converting DC power into AC power comprises in an enclosure of the electrical apparatus 1: a main board 20 on which a noise filter is mounted; a control circuit board 14 for performing conversion control; a metal tabular member 16 placed mutually facing the main board 20; and a communication board for communicating with an external device in a communication module 70. In the electrical apparatus 1, the grounding voltage of the main board 20, control circuit board 14, tabular member 16, and communication board is kept equal to the voltage of the enclosure, a power line is connected with an input side of the noise filter, after the power line flowing DC power in a space outside of the peripheral edge of the main board 20 not going through a projection space of the main board 20 is pulled around, and the communication board is placed at a position which is within the space outside of the peripheral edge and higher than the position of the tabular member 16 upward of the power line. |
