An electric detonating fuse assembly for preventing abnormal ignition caused by static electricity, which incorporates a tubular body member including an igniting charge and an explosive charge, a filament disposed in the vicinity of the igniting charge, terminal leads to supply igniting currents to the filament, and a non-linear resistor element disposed between the terminal leads and the tubular body member. The resistor element sets a critical point between the normal igniting voltage and the starting voltage of the sparking discharge. The resistor element presents a low resistance value upon application of a supply voltage greater than the voltage at the critical point.
