Chip type discharge element with laminated insulating sheets

摘要

A chip type discharge element which discharges when a voltage of a predetermined value or greater is applied thereto. It serves to protect electronic components and comprises at least one bored insulating sheet sandwiched in layers between two insulating sheets to thereby close therewith a bore formed at the bored insulating sheet, at least two electrode films provided thereon and extending from the bore to both lengthwise sides of the insulating sheets and partly facing each other across the bore, and exterior electrodes provided at the outer sides of the layered insulating sheets so that the electrode films are electrically connectible to the exterior end of the electrode films. The gap between electrode films opposite to each other across the bore at the bored insulating sheet can be controlled whereby a chip type discharge element discharging at low voltages is obtainable.
