Abstract
In the fabrication of a surge protector device which utilizes breakdown phenomena of a resistive film, a case which fixes metal bars in it, makes electrical contacts with the metal bars and contains oxidizing and refractory agents, a cap, metal bars and oxidizing and refractory agents are prepared in advance. In the fabrication process of the surge protector device using these elements, a step to control the force applied to the cap, the metal bars and the case so that the force applied to the interface between the resistive films and the mechanical contacts which form electrodes to the metal bars can be controlled. Automation process to fabricate the surge protector device will be realized and efficient fabrication of the precise surge protector device will be also realized. A surge protector device whose breakdown voltage is precisely controlled will be realized reproducibly.
