PURPOSE: A varistor module is provided to prevent damage to a varistor due to an over current by reducing power supply to a varistor small body when temperature of the varistor module is increased. CONSTITUTION: Terminal parts(110a,110b) are used as an input terminal and an output terminal. A varistor part is laminated on the top of the terminal parts. Electrode parts(130a,130b) are laminated on the upper surface of the varistor part. An element protection part(140) is laminated on the top of the electrode parts. A resistance value of the element protection part is increased when temperature of the varistor part is increased. The terminal parts comprise a pair of terminal patterns.
