Ignition apparatus for an internal combustion engine

An ignition apparatus for an internal combustion engine comprising:

• a casing;
• a closed magnetic circuit core incorporated in said casing and having sides;
• a primary coil arranged to surround part of the sides of said closed magnetic circuit core and having primary coil connector terminals at its opposite ends;
• a secondary coil arranged to surround said primary coil and having secondary coil connector terminals at its opposite ends for outputting a high voltage when a current supplied to said primary coil is turned on and off;
• a wiring module having module connector terminals connected with said primary coil connector terminals and being composed of a plurality of wires integrally formed with each other through a resin for supplying the current to said primary coil;
• a resin portion filled in said casing to fixedly attach said closed magnetic circuit core, said primary coil and said secondary coil to an inner surface of said casing;
• and positioning means arranged between said primary coil and said wiring module for positioning the relative positions of said primary coil connector terminals and said module connector terminals.
