Claim:
1. A resin-sealed semiconductor device comprising: a mesa-type semiconductor element which includes a mesa-type semiconductor base body having a pn-junction exposure portion in an outer peripheral tapered region which surrounds a mesa region, and a glass layer which covers at least the outer peripheral tapered region; and a molding resin which seals the mesa-type semiconductor element, wherein the mesa-type semiconductor element includes, as the glass layer, a glass layer which is formed by baking a glass composition for protecting a semiconductor junction which is made of fine glass particles prepared from a material in a molten state, the glass layer is formed using a glass composition which substantially contains none of Pb, P, As, Sb, Li, Na and K, the glass composition contains at least SiO the glass composition can be baked at 1100° C. or below, and (i) the content of SiO (ii) the content of SiO
