A silicon carbide semiconductor device, including a semiconductor substrate having first and second semiconductor regions and a plurality of third semiconductor regions sequentially formed therein, a plurality of trenches penetrating the second and third semiconductor regions, a plurality of gate electrodes provided in the trenches via a gate insulating film, an interlayer insulating film covering the gate electrodes, a plurality of contact holes penetrating the interlayer insulating film, a first electrode provided in the contact holes and at the surface of the interlayer insulating film, and a second electrode electrically connected to the first semiconductor region. The interlayer insulating film has a plurality of recessed parts and protruding parts, to thereby form at least three recesses and protrusions repeatedly at a surface of the interlayer insulating film. The first electrode includes first to third electrode films, the second electrode film having a shape reflecting the surface of the interlayer insulating film.
