A MOSFET includes: a SiC layer including one main surface and provided with a plurality of contact regions; and a plurality of source electrodes formed in contact with the contact regions. In the MOSFET, in a plan view of the one main surface, a plurality of cells including the contact regions and the source electrodes are formed adjacent to one another, each of the plurality of cells having an outer circumferential shape that is a shape of hexagon including a long axis. According to the MOSFET, a contact resistance between each contact region and each source electrode can be further reduced, thereby attaining a more improved electrical property.
