Abstract
The power conversion device includes: a main circuit having first and second wiring layers formed respectively on both surfaces of a base board, mounted parts mounted on the first and second wiring layers, and first and second GND layers formed respectively, between external- and internal-layer portions of the base board and in regions corresponding to the mounted parts each being a mounted part which forms a circuit other than a circuit having an inductance component as a lumped constant, and to the first and second wiring layers; and a cooler attached to the base board by means of fixing screws through a first through-hole created in an end portion of the board; wherein the first and second GND layers are each formed so that creepage distance is created around a second through-hole in which a lead insertion part that mutually connects the first and second wiring layers is inserted.
