An incandescent lamp (1) to be connected to a socket (11) includes a glass tube (2) having a sealing portion (5) at each end thereof, and a generally U-shaped lead portion (4a) connected to a filament (3) disposed in the glass tube (2) is projected from each sealing portion 5. A socket body (12) of the socket (11) includes a base portion (21) and a pair of socket portions (22) respectively rising from both ends of the base portion (21). Each socket portion (22) is provided with a sealing portion groove (27a) and a lead portion groove (27b), which are adapted to respectively permit the sealing portion (5) and the lead portion (4a) at the corresponding end of the incandescent lamp (1) to be removably inserted. A pair of feeding terminal pieces (34) of a lamp contact terminal (13) are disposed in each socket portion (22) at such a position as to face the lead portion groove (27b). With the configuration as above, when the incandescent lamp (1) is inserted and connected to the socket, the positions to which the respective lead portions (4a) of the incandescent lamp (2) are inserted can be easily set, by inserting the sealing portions (5) and the lead portion (4a), one each of which is provided at each end of the incandescent lamp (1), respectively into the sealing portion grooves (27a) and the lead portion grooves (27b) of the socket portions (22) at both ends of the socket (11). Then, each lead portion (4a) can be inserted between the pair of feeding terminal pieces (34) of the corresponding lamp contact terminal (13), which face the lead portion groove (27b).
