A reactor unit includes a plurality of reactors and a cooler. An inside of the cooler serves as a flow passage of refrigerant, and the reactors are mounted on an outside surface of a bottom plate of the cooler. The bottom plate separates the flow passage from an outside. A plurality of fins is provided on a surface of the bottom plate on the flow passage side. A flat portion in which the fins are not erected is provided in a first region and a second region. The first region is a region of the surface of the bottom plate on the flow passage side and corresponds to a space between a pair of coils of the reactor. The second region corresponds to each of four corners of each of the reactors in a plan view of the bottom plate.
