Abstract:
An LED lamp includes a board, a metal wiring provided on the board, an LED mounted on the metal wiring, and a metal heat dissipation film mainly made of a metal different from a metal for forming the metal wiring. The metal heat dissipation film partially overlaps the metal wiring. The metal heat dissipation film has an irregular surface. The metal heat dissipation film is mainly made of a metal that is softer than the metal wiring. The metal heat dissipation film intervenes between the board and the metal wiring, and part of the metal heat dissipation film that is in contact with the metal wiring has an irregular surface.
