Abstract: A voltage nonlinear resistive element 10 includes a resistor 14 containing a joined body 12 in which a zinc oxide ceramic layer 12a composed mainly of zinc oxide and having a volume resistivity of 1.0×10−1 Ωcm or less is joined to a bismuth oxide layer 12b composed mainly of bismuth oxide, and a pair of electrodes 16 and 18 disposed on the resistor 14 such that an electrically conductive path passes through a junction between the zinc oxide ceramic layer 12a and the bismuth oxide layer 12b. In this element 10, the zinc oxide ceramic layer 12a of the joined body 12 has a lower volume resistivity than before. This can result in a lower clamping voltage in a high-current region than before.
