IGNITION COIL FOR INTERNAL COMBUSTION ENGINE

摘要

An ignition coil (1) for an internal combustion engine is provided with: a coil section (2) including a primary coil and a secondary coil; and a connector case section (3). The primary coil is formed by winding a primary electric wire on the outer periphery of a resin primary spool (211). The connector case section (3) is provided with a terminal (4) consisting of a conductor and extending from the inside of the fitting hole thereof to a connector section. In the terminal (4), an insertion slit (42) is formed in the insertion section (41) of the terminal (4), the insertion section (41) being disposed within the fitting hole. The insertion slit (42) extends in the fitting direction (A) in which the coil section (2) and the connector case section (3) are fitted together. The winding end (213) of the primary coil (21) is led out substantially along the winding direction (B) of the primary electric wire and is inserted in the insertion slit (42) in the fitting direction (A).
