摘要： An ignition coil for internal combustion engine includes: a center core disposed on an inner side of a primary coil and a secondary coil and a side core disposed on an outer side of the primary and secondary coils whose one end face abuts on one end face of the center core and the other end face abuts on the other end face of the center core via a magnet. The side core is formed of a plurality of side core portions obtained by dividing laminated magnetic steel plates at different positions in a longitudinal direction thereof and has a superimposed portion in which the magnetic steel plates of the adjacent side core portions mutually superimpose between the different positions in the longitudinal direction. It thus becomes possible to provide an ignition coil for internal combustion engine capable of suppressing an increase of magnetic circuit resistance markedly without deteriorating assembly workability.
