Patent ID: 7649436

Claim:
A varistor body containing a varistor material, wherein the varistor material has a composition containing Zn, Co, Pr, Li, and Zr, and an analysis of the varistor body in the depth direction from the surface thereof gives a Li content of 0.08 parts by mass or less to 100 parts by mass of the sum of Zn, Co, and Pr contents at a level of 2 μm at the surface side above a reference depth where the Zr content becomes almost constant, wherein L 1 /L 2 is in a range from 1 to 2.20, where L 1 signifies parts by mass of the Li content to 100 parts by mass of the sum of Zn, Co, and Pr contents at a level of 2 μm at the surface side above the reference depth, and L 2 signifies parts by mass of the Li content to 100 parts by mass of the sum of Zn, Co, and Pr contents at the reference depth.
