Power Conversion Device

An object of the invention is to suppress that resistance against vibrations is reduced, while reducing the number of components. A power conversion device according to the present invention includes: a power semiconductor module that converts a DC current into an AC current; a plate conductor that transfers the DC current or the AC current; a resin sealing material that seals the plate conductor; and an electric component that is used to control the power semiconductor module, wherein the resin sealing material includes a supporting member that supports the electric component, and wherein the plate conductor is buried in a portion of the resin sealing material that is disposed to face the electric component.
