A method of producing a silicon carbide semiconductor device, including: step (A) of forming an impurity-doped region by implanting impurity ions 3 into at least a portion of a silicon carbide layer 2 formed on a first principal face of a silicon carbide substrate 1 having first and second principal faces; step (B) of forming capping layers 6 having thermal resistance on at least an upper face 2a of the silicon carbide layer 2 and on at least a second principal face 12a of the silicon carbide substrate 1; and step (C) of performing an activation annealing treatment by heating the silicon carbide layer 2 at a predetermined temperature.
