According to one embodiment, a semiconductor device includes a first main electrode, a control electrode, an extraction electrode, a second insulating film, a plurality of contact electrodes, and a control terminal. The first main electrode is electrically connected to a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type selectively provided on a surface of the first semiconductor region. The control electrode is provided on the first semiconductor region via a first insulating film. The extraction electrode is electrically connected to the control electrode. The second insulating film is provided on the first main electrode and the extraction electrode. The plurality of contact electrodes are provided in an inside of a plurality of first contact holes formed in the second insulating film and are electrically connected to the extraction electrode. The control terminal covers portions of the first main electrode provided on the first semiconductor region, on the second semiconductor region, and on the control electrode, respectively, and the extraction electrode, is electrically connected to the plurality of contact electrodes, and is electrically insulated from the first main electrode by the second insulating film.
