ABSTRACT:
In an ignition apparatus for an internal combustion engine, to reduce the size of the apparatus and improve the layout property for mounting the apparatus and a radiating property of the apparatus, a primary coil 2 and a secondary coil 4 are concentrically wound around the center core 6a of a magnetic core 6 of a closed magnetic circuit and accommodated in an outer case 15. A module accommodating portion 15a is provided with the outer case 15 and located at a position where it is overlapped with the side core 6b of the core 6 in a direction perpendicular to a surface of the closed magnetic circuit formed by the core 6 (axial direction of the core 6). Further, a connector 8 which feeds a primary current from an external power unit to the primary coil 2 is disposed integrally with the outer case 15 at a position where it is overlapped with the center core 6a in the axial direction of the core 6 as well as overlapped with the module accommodating portion 15a in a direction perpendicular to the axial direction of the core 6.
