An RC-IGBT includes a first electrode disposed on a first main surface of a semiconductor substrate over a transistor region and a diode region. The semiconductor substrate includes a MOS gate structure on a first main surface side in the transistor region. The RC-IGBT includes: an interlayer dielectric covering a gate electrode of the MOS gate structure, and having a contact hole exposing a semiconductor layer; and a barrier metal disposed in the contact hole. The first electrode enters the contact hole, is in contact with the semiconductor layer of the MOS gate structure through the barrier metal, and is in direct contact with a semiconductor layer in the diode region of the semiconductor substrate.
