ABSTRACT:
An ignition apparatus for an internal combustion engine can increase the degree of freedom of wiring paths of electroconductive wires as well as simplifying and miniaturizing a wiring module. Transformers (5A,5B,5C) are built into a casing (4) and each includes a core (6), a primary coil (8) and a secondary coil (10) arranged to surround the core for generating a high voltage in the secondary coil (10). A wiring module (20) built into the casing electrically connects the transformers and the switching module with one another. An insulating resin portion (11) fixedly attaches the transformers, the switching module and the wiring module to the casing. The wiring module (20) includes a module main body (22), which is formed by integrating a plurality of conductors (13, 14, 15) with one another through a resin, and flexible electroconductive wires (21) disposed along a surface of the module main body (22).
