A lamp with a light emission element arranged in a light-emitting tube, external leads for supplying energy to the light emission element, an antioxidant layer covering said external leads, sealing portions sealing metal foils connected electrically to the external leads and a base fixed via an adhesive to said sealing portions. The adhesive that fixes the base does not directly contact the antioxidant layer since an intermediate layer made of a material which does not react with the alkali in the adhesive is provided at a periphery of the antioxidant layer of the external lead, and the base is fixed by the adhesive being provided at an outer periphery of the intermediate layer.
