Two bus bars 13 having terminal parts 19 at their one ends 17 are arranged in parallel. Right and left contact spring pieces 23a, 24a on an upper stage of the terminal parts 19 of the bus bars 13 are connected to a pair of contact parts of a semiconductor light emitting element 25 which is disposed between the two bus bars 13, and right and left contact spring pieces 23b, 24b on a lower stage of the terminal parts 19 of the bus bars 13 are connected to a pair of contact parts of a Zener diode 27 disposed between the two bus bars 13. The terminal parts 19 of the adjacent bus bars 13 are provided with first rotation restricting parts 48 which are adapted to be contacted with both side faces of the semiconductor light emitting element 25 which is disposed between the two bus bars. |
