Abstract
A high-tension secondary current generated from an ignition coil is accumulated in a capacitor set at the head of a spark plug in a gasoline engine for automobiles, etc., and when the voltage of the discharging shaft at the end of the spark plug has built up to a predetermined value for discharge, the static electricity accumulated in the capacitor is discharged at a stroke to let out strong sparks.
