Abstract
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).
