PROBLEM TO BE SOLVED: To prevent a crack possibly produced by stress concentration, caused by a bent bobbin each time a resin dilates and contracts due to a temperature change etc., at a junction part between a bobbin cylinder and a barrier in the conventional igniter, in which resin mold is performed in a state of a step-up transformer housed in a casing, which may produce an uneven resin thickness surrounding the step-up transformer.SOLUTION: There are formed ridge-shaped reinforcement parts 61 to 63 extending on the surface of the barrier from the outer peripheral surface of the cylindrical part.SELECTED DRAWING: Figure 4 |
