摘要： PROBLEM TO BE SOLVED: To provide an ignition coil reduced in the size of a core constituting a magnetic path to permit miniaturization while securing ignition performance, and its manufacturing method. SOLUTION: An ignition coil 1 is provided with a center core 20, a secondary coil 24, a primary coil 26, and an outer peripheral core 27. The center core 20 is formed by stacking non-insulated silicon steel sheets 200 and double side insulated silicon steel sheets 201, and the outer peripheral core 27 is formed by stacking the non-insulated silicon steel sheets 270 and the double side insulated silicon steel sheets 271. Thereby, insulating films are not formed in superposed state between the adjacent silicon steel sheets, and the size in the direction that the center core 20 and the outer peripheral core 27 are stacked can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an ignition coil which can be miniaturized by reducing the cross section of the core. SOLUTION: The ignition coil has the core, a primary spool, a primary coil, a secondary spool and a secondary coil. In the core, a band-like directional silicon steel plate which is long in the easy magnetization direction is laminated in a plate thickness direction with its easy magnetization direction uniform, and furthermore, it is formed into a square shape, by bending along an easy magnetization direction. Consequently, the ignition coil can be made compact, by reducing the core by raising the saturation magnetic flux density of the core. COPYRIGHT: (C)2005,JPO&NCIPI
