Zusammenfassung:	The present invention can reduce an on-resistance while suppressing reduction in a short circuit capacity. The present invention includes a SiC epitaxial layer, a well region, a source region, a channel resistance adjusting region, a gate electrode, an interlayer insulating film, a source electrode, and a drain electrode. The channel resistance adjusting region is sandwiched between the source region and the SiC epitaxial layer in a surface layer of the well region. The channel resistance adjusting region is a region in which a first impurity region is intermittently formed in a direction intersecting a direction in which the source region and the SiC epitaxial layer sandwich the channel resistance adjusting region.
