VOLTAGE NONLINEAR RESISTIVE ELEMENT AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To increase voltage nonlinear index more than conventional, in a voltage nonlinear resistive element where other metal oxide area is in contact with a zinc oxide area.SOLUTION: A voltage nonlinear resistive element 10 includes a voltage nonlinear resistor (abbreviated as resistor) 20, and a pair of electrodes 14, 16 sandwiching the resistor 20. The resistor 20 has a structure laminating a first layer 21 mainly composed of zinc oxide, a second layer 22 mainly composed of zinc oxide, and a third layer 23 mainly composed of a metal oxide different from zinc oxide. The second layer 22 is in contact with the first layer 21, thinner than the first layer 21, and having a volume resistivity higher than that of the first layer 21. The third layer 23 is in contact with the second layer 22.SELECTED DRAWING: Figure 1
【課題】酸化亜鉛領域に他の金属酸化物領域が接している構造の電圧非直線抵抗素子において、従来に比べて電圧非直線指数を大きくする。【解決手段】電圧非直線抵抗素子１０は、電圧非直線抵抗体（抵抗体と略す）２０と、この抵抗体２０を挟み込む一対の電極１４，１６とを備えている。抵抗体２０は、酸化亜鉛を主成分とする第１層２１と、同じく酸化亜鉛を主成分とする第２層２２と、酸化亜鉛とは異なる金属酸化物を主成分とする第３層２３とが積層された構造のものである。第２層２２は、第１層２１に接しており、厚みが第１層２１より薄く、体積抵抗率が第１層２１より高い。第３層２３は、第２層２２に接している。【選択図】図１
