ABSTRACT:
An ignition apparatus for an internal combustion engine, comprises, an ignition coil including a primary coil and a secondary coil for generating a peaked high-voltage output from an abrupt input-current decrease in the primary coil, and an extension device which extends from the ignition coil to supply the peaked high-voltage output to a spark plug, wherein a part of an outer periphery of the secondary coil at an intermediate position of the outer periphery of the secondary coil sinks in relation to the other part of the outer periphery of the secondary coil to form a groove extending in a radial direction of the secondary coil, the peaked high-voltage output is transmitted from the secondary coil through the groove to the extension device, and the extension device includes a first member extending from the ignition coil, a second member for being connected to the spark plug and an elastic member connecting the first member to the second member so that the first member moves elastically in relation to the second member.
