A power conversion device that can be made smaller without degradation of its cooling performance is provided. This power conversion device includes a power semiconductor module that converts DC current into AC current, a capacitor for smoothing DC power, a first flow conduit defining member for defining a first flow conduit and for defining a first storage space in which the power semiconductor module is housed, and a second flow conduit defining member for defining a second flow conduit and for defining a second storage space in which the capacitor is housed. When viewed from above the power conversion device, the first flow conduit defining member and the second flow conduit defining member are arranged so that a projecting portion of the first flow conduit defining member and a projecting portion of the second defining body do not overlap; the first flow conduit defining member is disposed beneath a plane that coincides with the lower surface of the second flow conduit defining member; and a first space, in which a vehicle component that is different from the power conversion device is disposed, is defined in a space to the side of the first flow conduit defining member and below the second flow conduit defining member. |
