An electric lamp device which is capable of suppressing obstruction light toward the sky even if being used as a garden light or the like as well as a common lighting electric lamp. In the electric lamp device comprising an envelope and a small-sized light-emitting element assembly, an open end of a globe is coupled to a globe connection opening of a base body to constitute the envelope, and the small-sized light-emitting element assembly, such as a set of baseless small-sized electric lamps connected in series to each other, is housed within this envelope, and additionally, a louver including ring-like louver components is put within the envelope surrounding the small-sized light-emitting element assembly. Further, when needed, an attachment is fixed in the globe connection opening of the base body. The louver is mounted on this attachment. The attachment is composed of a plate section, a light-emitting element mounting section, and a support standing section. The small-sized light-emitting element assembly is mounted on the light-emitting element mounting section, and is supported by a support.
