In order to provide a power conversion device having a semiconductor switching element and capable of achieving both noise countermeasures and the suppression of switching surges, in the power conversion device, which is provided with a power conversion unit that outputs a voltage resulting from switching and converting by means of the semiconductor switching element a DC voltage supplied by means of a negative line and a positive line of a DC power source, a plurality of inter-line capacitors are connected in parallel between the positive line and the negative line, the plurality of inter-line capacitors have a capacitance that has a lower value the closer the position of connection to the power conversion unit, and the inter-line capacitor having the lowest capacitance value is set to a value greater than the capacitance between primary electrodes during imposition of DC voltage to the switching element used in the power conversion unit.
