PROBLEM TO BE SOLVED: To provide an ignition coil in which the mold resin is less likely to be cracked even if the ignition coil is made compact.SOLUTION: An outer peripheral core 40 abutting against a center 30 and forming a closed magnetic circuit is configured to have a core central part 40a located above a secondary coil L2, and a first protrusion 40b projecting downward from the tip of the core central part 40a and facing an ignitor TR. The surface of the first protrusion 40b facing the ignitor TR is coated with an elastic body ER in a contact state, and a cover 3 large enough to conceal the ignitor and the outer peripheral core, in the plan view, is located above the ignitor TR and the outer peripheral core 40. |
