Abstract:
1. A disc varistor, comprising: a first ceramic body having a disc shape, with a first electrode provided on a first surface of the first ceramic body and a second electrode provided on a second surface of the first ceramic body; a second ceramic body having a disc shape, with a third electrode provided on a first surface of the second ceramic body and a fourth electrode provided on a second surface of the second ceramic body, the third electrode being arranged to face the second electrode of the first ceramic body; a first lead wire interposed between the second and third electrodes, and electrically connected to the second and third electrodes; and a second lead wire, comprising: a body portion electrically connected to the first electrode of the first ceramic body; a first extension provided by bending the second lead wire at a predetermined position thereof, the first extension extending from the body portion to the second ceramic body, and being spaced apart from outer circumference of the first and second ceramic bodies; and a second extension provided by bending the second lead wire at a predetermined position thereof, the second extension extending from the first extension to the fourth electrode of the second ceramic body, and being electrically connected to the fourth electrode of the second ceramic body.
