Abstract
In a semiconductor device, a first lead frame and a second lead frame are fixed to a metal conductor base by an organic insulating film made of a polyimide-based material. The organic insulating film satisfies relationships of t>tand t>t, where tis a thickness of a portion of the organic insulating film sandwiched between the metal conductor base and the first lead frame, tis a thickness of a portion of the organic insulating film sandwiched between the metal conductor base and the second lead frame, and tis a thickness of a portion of the organic insulating film that is not sandwiched between the metal conductor base and the first lead frame and is not sandwiched between the metal conductor base and the second lead frame.
