A MOSFET which is a semiconductor device capable of achieving a stable reverse breakdown voltage and reduced on-resistance includes a SiC wafer of an n conductivity type, a plurality of p bodies of a p conductivity type formed to include a first main surface of the SiC wafer, and n+ source regions of the n conductivity type formed in regions surrounded by the plurality of p bodies, respectively, when viewed two-dimensionally. Each of the p bodies has a circular shape when viewed two-dimensionally, and each of the n+ source regions is arranged concentrically with each of the p bodies and has a circular shape when viewed two-dimensionally. Each of the plurality of p bodies is arranged to be positioned at a vertex of a regular hexagon when viewed two-dimensionally.
