Abstract
In a surge absorber, capable of suppressing a voltage surge and a current surge together without interrupting a signal transmission, an input electrode and an output electrode are spaced apart on the surface of a varistor substrate, and a resistance element is connected between the electrodes. A ground electrode is provided on the reverse side of the varistor substrate so as to face the input electrode with the varistor element therebetween. Thereby, a varistor element is formed by the input electrode and the ground electrode where a voltage surge and a current surge can be suppressed by the resistance element, and where a signal waveform is not weakened by capacitance of the varistor element, and ordinary signal transmission is not interrupted.
