摘要： PROBLEM TO BE SOLVED: To provide an internal cornbustion engine ignition coil which is enhanced in insulation durability in a high-temperature environment. SOLUTION: An ignition coil 2 is so formed as to be housed in a plug hole provided to each cylinder and composed of a cylindrical transformer 5, a control circuit 7 which is located at the one edge of the transformer 5 and interrupts the primary current of the transformer 5 intermittently, a case 100 which is capable of housing the transformer 5, the control circuit 7, and the others, and a connector 6 which is located at the other edge of the transformer 5 and feeds the secondary voltage of the transformer 5 to an ignition plug. The case 100 is made of PPS(polyphenyl sulfide) which comprises 15 to 40% by weight of glass fiber and formed like a cylinder shaped in one piece with the connector 6 through injection molding. By this setup, the case 100 can be more enhanced in insulation durability than that made of PBT (polybutylene terephthalate) and increased in tensile strength in a high-temperature environment.
