CONSTITUTION: A trigger coil includes a coil(101), an output portion(104), a winding guider(108), and a winding off-track preventer(116). The coil includes a ground portion(103), having a first junction portion(113) having a first collector(105) and a plating portion on a right portion of the core and a second junction portion(114) having a second collector(106) and another plating portion, on a right portion thereof. The output portion includes a third junction portion(115) having a third collector(107) and the other plating portion on a left portion of the core. The winding guider and the winding off-track preventer are implemented on upper portions of the left and right portions of the core, respectively.
