Beschreibung
Zusammenfassung:	Disclosed is a heat dissipating member (1) for an LED light bulb that has a built-in LED element. The heat dissipating member (1) is formed by press-molding an aluminum alloy plate into a generally conical shape, and the outer circumferential surface (10) of the heat dissipating member (1) is provided with recessed and projected portions (12). The aluminum alloy plate is a pre-coated aluminum alloy plate that is obtained by pre-coating both surfaces or one surface of a substrate with a synthetic resin coating film. At least one of the pre-coated synthetic resin coating films preferably comprises a heat-dissipating coating film which contains a heat-dissipating substance in a base resin that has a number average molecular weight of 10,000-40,000 and is composed of one or more resins selected from among urethane resins, ionomer resins, polyethylene resins, epoxy resins, fluororesins and polyester resins.
