A circuit for EMC 1 in a power input circuit includes at least two wirings of a high-potential-side wiring 2 and a low-potential-side wiring 3 having different potentials and formed on a circuit board, a cutoff part 6 having one end connected to the high-potential-side wiring 2, a capacitor 10 connected between the other end of the cutoff part 6 and the low-potential-side wiring 3, a cutoff part 7 having one end connected to the high-potential-side wiring 2, a capacitor 20 connected between the other end of the cutoff part 7 and the low-potential-side wiring 3, and a capacitor 30 connected between a connection part 4 where the cutoff part 6 and the capacitor 10 are connected and a connection part 5 where the cutoff part 7 and the capacitor 20 are connected. This can reduce the number of capacitors while preventing a decrease in the capacitance.
