A surface mounted light emitting device having superior reliability with a focus on low cost producibility, in which a protective element can be formed without lowering the efficiency of light emission from a light emitting element, is provided.Since, for example, a printed resistance 16, as a protective element, is formed on at least the top surface side, the back surface side, or the inside of an insulating film 2 and, for example, the printed resistance 16, as a protective element, is formed on the rear surface side of the installation surface of a light emitting element 11, light emitted from the light emitting element 11 is not obstructed due to light blocking, light absorption or the like by, for example, the printed resistance 16, as a protective element.
