A resin sealed semiconductor device includes a first semiconductor switching device having a first emitter terminal and a first collector terminal bonded to its top and bottom surfaces respectively, a second semiconductor switching device having a second emitter terminal and a second collector terminal bonded to its top and bottom surfaces respectively, a first heat sink directly or indirectly bonded to the first collector terminal, a second heat sink directly or indirectly bonded to the second collector terminal, and a molding resin integrally covering the first and second semiconductor switching devices. The first and second heat sinks are exposed from the molding resin. The first emitter terminal faces and is spaced apart from the second emitter terminal.
