1. a nonlinear resistance (10), being included as electric current provides the zinc oxide valve plate sintered body of passage, the side of this sintered body has resistive formation (12,14) and on sintered body, the lower end has electrode (16,18), it is characterized in that:

  • above-mentioned side high-resistance layer (12,14) comprise silicon, antimony, bismuth and lithium, from the side to the degree of depth be 200 μ

    m the zone in average composition be silicon (for silicon dioxide) 5-70mol%, antimony (for antimonous oxide) is 2-30mol%, bismuth (for bismuth oxide) is 2-10mol%, lithium (for lithium carbonate) is that 0.01-5mol% and zinc (for zinc oxide) are 10-90mol%, above-mentioned side high-resistance layer (12,14) is by near the first side high-resistance layer (12) and the adjacent first side high-resistance layer of side surface and have the second side high-resistance layer (14) low than the resistivity of the first side high-resistance layer and form.
