A power conversion device includes a negative side wiring and a positive side wiring. The positive side wiring is provided with a coil of a motor. The power conversion device uses a coil to boost a DC voltage. The power conversion device includes a Y capacitor provided between the positive side wiring and a ground, and a Y capacitor having a capacitance larger than capacitance of the Y capacitor and provided between the negative side wiring and the ground.
