Abstract
An igniter controls a current flowing in a coil unit for supplying a high voltage to a spark plug for use in an internal combustion engine. The igniter includes: a pyrogenic power element, a metal block, a lead frame, and a controller. The lead frame electrically connects the metal block and the coil unit to each other. The controller controls the operation of the power element. The power element is fixed directly to the metal block by soldering at a surface of the power element on one side, and is electrically connected to the controller at a surface of the power element on the other side. With this configuration, heat generated during the operation of the power element is transferred smoothly in a moment to the metal block. As a result, temperature increase at the power element is suppressed during the operation of the power element.
