Claim Text:
1. A semiconductor device comprising: a semiconductor element including an obverse surface and a reverse surface spaced apart from each other in a thickness direction; a main lead supporting the semiconductor element via the reverse surface; and a resin package covering the semiconductor element and the main lead; wherein the main lead is exposed from the resin package, wherein the semiconductor element includes a part that does not overlap the main lead as viewed in the thickness direction, wherein the main lead includes a main-lead obverse surface and a main-lead reverse surface that face in mutually opposite directions, the semiconductor element is disposed on the main-lead obverse surface, and the main-lead reverse surface is exposed from the resin package, wherein the main lead includes a main-lead full-thickness portion and a main-lead eaved portion, the main-lead full-thickness portion extends from the main-lead obverse surface to the main-lead reverse surface, and the main-lead eaved portion projects from the main-lead full-thickness portion in a direction perpendicular to the thickness direction, wherein the semiconductor device further comprises a first sublead electrically connected to the semiconductor element, wherein the first sublead is spaced apart from the main lead and exposed from the resin package, wherein the main-lead eaved portion includes a main-lead front portion projecting from the main-lead full-thickness portion in a direction toward the first sublead, wherein the main-lead eaved portion includes a main-lead side portion projecting from the main-lead full-thickness portion in a direction perpendicular to the direction in which the main-lead front portion projects, and wherein the main lead includes a main-lead side connecting portion projecting from the main-lead side portion, the main-lead side connecting portion including an end surface exposed from the resin package.
