A MOSFET includes a silicon carbide substrate including a main surface having an off angle of not less than 50° and not more than 65° with respect to a {0001} plane, a buffer layer and a drift layer formed on the main surface, a gate oxide film formed on and in contact with the drift layer, and a p type body region of a p conductivity type formed in the drift layer to include a region in contact with the gate oxide film. The p type body region has a p type impurity density of not less than 5×1016 cm−3.
