Abstract
The object is to provide a technology for enabling reduction of adhesion of a bonding material to a particular electrode. A semiconductor device includes: a semiconductor element with a surface including a first electrode and a second electrode; a protective film formed on the surface of the semiconductor element and having insulating properties, the protective film exposing the first electrode and the second electrode; a metal lead electrode bonded to the first electrode exposed from the protective film; and a bonding material with which the first electrode exposed from the protective film is bonded to the metal lead electrode. The metal lead electrode includes an abutment portion being a protrusion abutting the protective film and blocking between the bonding material and the second electrode in a cross-sectional view.
