A lamp ( 14 ) has an inner tube ( 32 ) pinch sealed at one end to form a pinch seal ( 82 ), to which a base ( 36 ) is attached. The base ( 36 ) has a pair of base pins ( 102, 104 ) provided in parallel to the axis of the inner tube ( 32 ). A pair of connection wires ( 98, 100 ) that extend out from the pinch seal ( 82 ) are inserted into the respective base pins ( 102, 104 ) and are fixed by concavities located in a portion of the base pins ( 102, 104 ). Each of the concavities is concave in a direction orthogonal to the base pins ( 102, 104 ) and parallel to an imaginary plane that traverses central axes of the base pins ( 102, 104 ). |
