Abstract: PROBLEM TO BE SOLVED: To provide an ignition coil which can generate a desired high voltage by suppressing the occurrence of cracks in an insulating resin material near inner peripheral angular sections at the end sections of an outer peripheral core in the axial direction without increasing the physical constitution of the coil in the radial direction. SOLUTION: In an ignition coil for an internal combustion engine, an attaching section 23b is formed at the end section of a primary spool 23 positioned on the low- voltage side of a secondary coil 21 and a ring member 51 is put on the attaching section 23b. Then an outer peripheral core 25 is put on the outer peripheral side of a primary coil 24, and inner peripheral angular sections at both end sections of the core 25 in the axial direction are respectively covered with rubber ring members 50 and 51. Since the ring members 50 and 51 prevent an epoxy resin from coming into direct contact with the inner peripheral angular sections at both end sections of the core 25, the occurrence of cracks in the resin 26 near the inner peripheral corner sections due to temperature fluctuation can be suppressed. Since the discharge between the core 25 which is a low-voltage section and a high-voltage section is suppressed, this ignition coil can impress a desired high voltage upon an ignition plug.
