Abstract: A winding rod 104a of a bobbin 104 around which a winding 103 of an induction coil 109 is wound is inserted into a re-entrant part 120 of a luminous bulb 101. Plural projections 108, 108, . . . are provided on the winding rod 104a. These projections 108, 108, . . . project toward the wall surface of the re-entrant part 120 beyond the winding 103 of the induction coil 109. The winding 103 of the induction coil 109 is formed closer to the winding rod 104a than a virtual line linking between the adjacent corners of the adjacent projections 108 and 108 in the circumferential direction of the winding rod 104a.
