PROBLEM TO BE SOLVED : To provide a voltage non-linear resistor porcelain that can achieve an excellent varistor characteristic, and is usable for a component such as an on-vehicle component or the like to which high moisture resistance is required.SOLUTION : A voltage non-linear resistor porcelain contains oxide of Zn, oxide of Co, oxide of R (specific rare earth), oxide of Cr, oxide of M1 (Ca, Sr), oxide of M2 (Al, Ga, In), and strontium titanate. The content of oxide of Zn is equal to 100 parts by mol, the content of oxide of Co ranges from 0.30 to 10 parts by mol, the content of oxide of R ranges from 0.10 to 10 parts by mol, the content of oxide of Cr ranges from 0.01 To 2 parts by mol, the content of oxide of M1 ranges from 0.10 to 5 parts by mol, the content of oxide of M2 ranges from 0.0005 to 5 parts by mol and the content of strontium titanate ranges from 0.10 to 5 parts by mol. When the content of oxide of Sr is set to α parts by mol and the content of barium titanate is set to β parts by mol, β≤0.10 and/or α×β≤0.18 is satisfied.SELECTED DRAWING : NoneCOPYRIGHT : (C)2017, JPO&INPIT
