    摘要： A varistor comprises an element body, two external electrodes, and a metal conductor. The element body includes a portion having first and second faces opposing each other. Two external electrodes are arranged on the first face of the element body. The metal conductor is arranged on the second face of the element body. The metal conductor has a thermal conductivity higher than that of the element body. At least a region between the two external electrodes and metal conductor in the element body exhibits a nonlinear current-voltage characteristic. The heat transmitted to the varistor is efficiently diffused from the metal conductor in the varistor.

    摘要： In a varistor, a heat radiating portion contains the same components as ZnO that is the main component of a varistor element body, as metal oxides, thereby, the structural components of the varistor element body and the heat radiating portion are caused to be common. During firing, Ag contained in the heat radiating portion diffuses into the grain boundaries of ZnO, near the interface between surfaces of the heat radiating portion and the varistor element body. Consequently, in the varistor, cracks hardly occur between the varistor portion and the heat radiating portion during firing (or during binder removal), thereby, ensuring sufficient bonding strength between the varistor portion and the heat radiating portion. Therefore, heat conducted to the varistor portion is radiated efficiently conducting through electrically conducted paths formed in the heat radiating portion from the surface facing the varistor element body to other three surfaces of the heat radiating portion.

    摘要翻译： 在变阻器中，散热部包含与作为金属氧化物的可变电阻元件主体的主要成分的ZnO相同的成分，因此使可变电阻元件主体和散热部的结构成为普通的。 在烧成期间，散热部中的Ag扩散到ZnO的晶界附近，靠近散热部和可变电阻元件主体的表面之间的界面。 因此，在压敏电阻中，在烧结（或者去除粘合剂期间）在变阻器部分和散热部分之间几乎不发生裂纹，从而确保了可变电阻部分和散热部分之间的充分的接合强度。 因此，传导到变阻器部分的热量从形成在散热部分的导电路径从与压敏电阻元件主体相对的表面有效地传导到散热部分的其它三个表面。
