ル。[Claims for Utility Model Registration] In the inner periphery of a bobbin of a primary coil in which a secondary coil is fitted concentrically to the outside, gap-forming legs of two pairs of iron cores for forming a closed magnetic path are attached from each end. In a closed magnetic circuit type ignition coil which is inserted and maintains a gap between the end faces of the gap forming legs of both iron cores in the inner periphery of the bobbin, the gap forming position is thickest on the inner surface of the bobbin of the primary coil, and the gap is thickest at each end. A closed magnetic circuit characterized in that an inwardly facing chevron portion whose thickness gradually decreases toward the end is provided, and each end of the gap forming leg of each core is provided with an inclined surface corresponding to the slope of the chevron portion. type ignition coil.
