Original Abstract Submitted

A silicon carbide semiconductor device includes a silicon carbide substrate having a first main surface; a first electrode formed on the first main surface; and a plating film formed on the first electrode, wherein a first irregularity is formed on a surface of the plating film, and H1/H2 is 0.10 or less, where H1 is a difference between a maximum value of a distance to a top of the first irregularity from the first main surface and a minimum value of a distance to a bottom of the first irregularity from the first main surface, and H2 is a minimum value of a thickness of the plating film.
