<p><P>PROBLEM TO BE SOLVED: To provide an igniter having an ion current detection function which is capable of suppressing generation of migration and miniaturized, and having an ion current detection function with superior engine mountability. <P>SOLUTION: In a ceramic substrate in which a low-voltage signal wire and a high-voltage power supply wire are not physically separated from each other on the same substrate with both sides being wired, one side of the substrate is fixed onto a heat sink with an adhesive, a terminal of the heat sink is fixed with an adhesive to the inside of an insert-molded container-shaped connector, and the terminal and a substrate input-output pattern are subjected to bonding connection by an aluminum wire. The substrate, the heat sink, the aluminum wire, and the terminal are molded with an epoxy resin filled inside the connector, and further molded with an ignition coil filling resin inside an ignition coil. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
