ABSTRACT:
Disclosed is an ignition apparatus for an internal combustion engine including a power switch 20 for intermittently feeding a primary current to an ignition coil, a primary coil 5 and a secondary coil 6 of the ignition coil being contained in an insulation case 1 with the power switch 20, primary coil 5 and secondary coil 6 being fixed by an insulating resin material 15 poured into the insulation case 1, the ignition apparatus comprising a shield plate 23 interposed between the secondary coil 6 and the power switch 20 to shield the power switch 20 from electromagnetic waves. With this arrangement, there can be obtained an ignition apparatus for an internal combustion engine by which the malfunction of the power switch and the like caused by electromagnetic waves generated at the ignition coil can be prevented.
