Abstract
An object is to provide a technique capable of suppressing a corrosion of a first electrode and a second electrode. A semiconductor element includes a semiconductor substrate, an Al electrode, a polyimide member selectively disposed on the Al electrode, and an Ni electrode. The polyimide member includes a protruding part which protrudes in a plane direction of an upper surface of the Al electrode and which has a lower portion having contact with the Al electrode in a cross-sectional view, in at least part of a peripheral part of the polyimide member in a top view. The Ni electrode is disposed on the Al electrode and the protruding part.
