Light emitting apparatus
A light emitting apparatus includes a light emitting device mounted on a base. First and second leads are electrically connected to the light emitting device. A first resin molding member formed of thermosetting resin covers at least partially the base and the first and second leads so that the first resin molding member is formed integrally with the base and the first and second leads. A second resin molding member formed of thermosetting resin is in contact with at least a part of the first resin molding member and covers the light emitting device. A recessed portion is formed in the first resin molding member on a light emitting device mount surface side of the base to open upward and to have a side surface. A protection device is mounted on the first lead or the second lead. The protection device is covered by the first resin molding member.
