Abstract: An electronic component composed of alternating internal electrodes in a ceramic material, the internal electrodes being electrically connected to an external electrode on each end of the ceramic material. The ceramic surface is porous and the surface between the external electrodes is impregnated with an insulating layer that also covers the surface of the body and the edges of the external electrodes to prevent water from finding its way through the edge of the external electrode.

Abstract: The present invention aims to present an electronic component which is free from the fear of sneaking-in of water etc. from the edge of electrode, by covering the electrode edge with resin. For the purpose, external electrodes (3) are formed at both ends of varistor (1) comprised of ceramic sheet (1a) and internal electrode (2) laminated alternately, and then, a within-the-surface insulation layer (30) is formed by covering the porous surface inside the varistor (1), or filling the porosity, with silicone resin, and an outside-the-surface insulation layer (31) is formed covering the surface of varistor (1) and the edge of external electrode (3).
