Abstract:
Provided is a resistive element which is excellent in inrush current resistance even in the case of having a surface-mountable small chip shape. The resistive element has an element main body composed of a semiconductor ceramic in which a main constituent thereof is composed of a Mn compound represented by the general formula (Nd1-xMx)yBazMn2O6 (M is at least one rare-earth element selected from Sm, Gd, Eu, Tb, Dy, Ho, Er, and Y), and x, y, and z respectively meet the conditions of: 0.05≦x≦0.4; 0.80≦y≦1.2; and 0.80≦z≦1.2 in the chemical formula.
