ABSTRACT:
Disclosed is an engine igniting coil device which comprises a plurality of coil units arranged in a case and unitarily potted therein with thermosetting resin, and is characterized by that a core portion of each coil unit is covered with a core cover, a coil base is mounted in the case to enclose portions of the core covers extruding from the coil case and inner space of the coil case is divided by partitions to separately accommodate coil units, thereby a required amount of resin for potting is reduced and thermal crack resistance of the resin potions is increased.
