Abstract

Abstract A connecting structure for the high voltage resistance wire used to feed a high voltage to, for instance, the ignition plug of an engine, has a high voltage resistance wire for noise suppression which has on one end a connecting terminal which can be fitted to a high voltage terminal that has a cylindrical insulator on its circumference. An insulating soft elastic cap is attached to the high voltage resistance wire and surrounds the connecting terminal, which is fitted to the high voltage terminal. The cap also is fitted to the cylindrical insulator of the high voltage terminal. A rigid holder is inserted on the outside of the elastic cap, and is fitted closely to the outer periphery of the connecting portion of the elastic cap and the cylindrical insulator.
