An ignition apparatus for an internal combustion engine includes a central core, a primary coil and a secondary coil arranged outside of the central core, a magnet arranged in abutment with one end face of the central core and magnetized in a direction opposite to the direction of a magnetic flux generated by energization of the primary coil, a side core arranged outside of the first and second primary coils so as to cooperate with the central core and the magnet to form a closed magnetic circuit, and a flexible core cover arranged to cover the side core. The side core includes a first side core section and a second side core section which have their one end faces arranged in abutment with each other. The first and second side core sections have their other ends in abutment against the magnet and the other end face of the central core, respectively.
