The straight-tube lamp 13 includes: a straight tubular cover 20 which accommodates a semiconductor light emitting element and which has translucency at least at one part; and a base 23 arranged at both ends of the cover 20. At an end surface of the base 23, a pair of lamp pins 30, whose tips protrude toward outside direction respectively, is protrusively formed, and also a protrusion 31 for erroneous attachment prevention is protrusively formed. The socket 14 attaches the straight-tube lamp 13 by rotating the straight-tube lamp 13 in which the pair of lamp pins 30 is inserted from outside surface and arranged in the front surface side. The socket 14 includes a recess part 63 in which the protrusion 31 for erroneous attachment prevention is inserted and rotationally moved according to the insertion and the rotation of the pair of lamp pins 30. |
