Abstract

A globe (11) and a substrate (12) form an outer shell (1). In the outer shell (1), there is arranged an attachment (3) having an electric lamp mount (32) and a support stand part (33). In the electric lamp mount (32) of the attachment (3), there is arranged a serially connected body of no-base type small electric lamps (4), and at the support stand part (33), there is arranged a support body (5). The serially connected body of no-base type small electric lamps (4) has a plurality of no-base type small electric lamps (51) and conductors (52) for serially connecting these no-base type small electric lamps (51), is composed by gathering these plurality of no-base type small electric lamps (51). The support body (5) supports the serially connected body of no-base type small electric lamps (4). Since the serially connected body of no-base type small electric lamps (4) that is contained within the outer shell (1) is supported by the support (5), it is possible to improve vibrationproof of the serially connected body of no-base type small electric lamps (4) and support the serially connected body of no-base type small electric lamps (4) in a prescribed position within the outer shell (1).
