Abstract
A spark coil includes: a center core; a primary coil disposed on an outer periphery of the center core; a secondary coil disposed on an outer periphery of the primary coil; and an output terminal electrically connected to the secondary coil. The secondary coil includes a tubular secondary bobbin having a plurality of flanges on an outer peripheral side thereof, a secondary conductive wire wound around the secondary bobbin, and a long-sheet-shaped secondary lead terminal having one and another end portions electrically connected to the secondary conductive wire and the output terminal, respectively. The secondary lead terminal is disposed, between corresponding ones of the flanges, in surface contact with none of side surfaces of the flanges.
