10大きさと端子電極42L。Problems to be Solved by the Invention In such a conventional configuration, with the recent miniaturization of electronic components, the thickness of the substrate 1 used for thick film varistors has become limited. The area occupied is also the size of the substrate 10 and the terminal electrode 42L.
4bの大きさにより制限されるため、エネルギー耐量が
低下するという問題が生じていた。Since it is limited by the size of 4b, there has been a problem that the energy withstand capacity is reduced.
本発明はこのような問題点を解決するもので、エネルギ
ー耐量のより大きい厚膜バリスタを提供することを目的
とするものである。The present invention is intended to solve these problems, and aims to provide a thick film varistor with greater energy resistance.
問題点を解決するための手段

である。Means for Solving the Problem In order to solve this problem, the present invention provides a varistor film consisting of a varistor layer and a pair of electrodes on the upper surface of the substrate, and a terminal electrode connected to the electrode on the side surface of the substrate. It was established.
作用
この構成により、従来より端子電極が位置していた面積
をバリスタ膜として使用できるためバリスタ膜の面積が
より大きくなることになる。Effect: With this configuration, the area where the terminal electrodes were conventionally located can be used as the varistor film, so the area of the varistor film becomes larger.
