摘要：A booster (2) is composed of a piezoelectric transducer including a combinationof a primary side piezoelectric element (5) and a secondary side piezoelectric element (6)wherein input electrodes (7, 8) and an output electrode (9) are provided in the thicknessdirection and length direction, respectively. The booster (2) is contained in a plug cap (3).The plug cap (3) covers a spark plug (4) from one end thereof. In such a state, a primaryvoltage having a natural resonance frequency of the piezoelectric element or a waveformidentical to a component waveform thereof is applied from a primary voltage generatingmeans (1) to the input electrodes (7, 8). At this time, the booster (2) directly imparts asecondary high voltage from the output electrode (9) to the spark plug (4) by thepiezoelectric effect, to generate a spark discharge in a discharge gap in a combustionchamber. This ignition system can be made smaller in size and weight at a lowmanufacturing cost.
