Abstract

PURPOSE:To prevent the deterioration due to the oxidation of a connected part to maintain circuit function over a long period by covering a non-linear resistance element that is contained inside a base and the connected part between said element and lead wires in a coated layer comprising a heat resisting inorganic material. CONSTITUTION:A negative resistance element 15 as a non-linear resistance element is contained in a base 4. This negative resistance element 15 is connected with external lead wires 5a, 5b via lead wires 16a, 16b, and connected in parallel with a light emission tube 8. This negative resistance element 16 and lead wires 16a, 16b are connected each other via metallic solder 17, and a coated layer 18 comprising a heat resisting inorganic material is formed over the outer surface of the element 15 itself and the connected part among the element 15 and lead wires 16a, 16b. Hereby, it is possible to prevent the deterioration due to the oxidation over the connected portion to maintain circuit prevention function over a long period, preventing the dielectric breakdown of an instrument, etc.
