A light emitting device has a base comprising at least one pair of leads having a silver-containing layer on their surfaces and being secured by a resin molded body, a light emitting element mounted on said leads, a protective film made of an inorganic material that covers the upper surface of said base, and a sealing resin disposed on the base surface via said protective film. The sealing resin has a first resin that covers said light emitting element, and a second resin having a higher hardness than said first resin that covers the boundaries between said resin molded body and said leads.
