PROBLEM TO BE SOLVED: To provide an ignition coil for internal combustion engines, which can cope with miniaturization and improvement in output. SOLUTION: In the ignition coil where a drive current supplied to the ignition coil is set higher than conventional, the same sectional area as that of the primary conductor of one winding of the conventional primary coil should be realized, and at least two primary conductors whose diameter is fixed are wound around a primary bobbin in parallel. |
