Abstract:
A lamp (1) comprises a light emitting unit (14b), a power source line (23a) which configures a power supply path to the light emitting unit (14b), a metal cap (50) which is formed in a cylindrical shape which is closed on end and with a screw groove (51a) disposed on the inner circumference face of the metal cap (50), and a circuit case (60) further comprising a metal cap attachment part (63) to which the metal cap (50) is attached. The metal cap attachment part (63) has a cylindrical shape and has a screw peak (61) protruding on the outer circumference face which is capable of screwing together with the screw groove (51a). The screw peak (61) is formed in a shape in which a plurality of notch parts (60a) aligns in the cylindrical axis direction. The power source line (23a) follows the inner side of the metal cap attachment part (63) and is folded back from the aperture (66) of the metal cap attachment part (63) along the outer circumference face (63a), and is positioned in a state in which the power source line (23a) passes through the inner side of each of the notch parts (60a), with the power source line (23a) being sandwiched between the metal cap attachment part (63) and the metal cap (50) thereupon. The central axis of the power source line (23a) which is present within the notch parts (60a) is in a lower location than the top part of the screw peak (61).
