ABSTRACT:
TECHNICAL FIELD
The present invention relates to electronic components such as a multilayer varistor, and a method of manufacturing the same.
BACKGROUND ART
A conventional electronic component having at least a pair of electrodes on the surface of body is impregnated with resin on the surface only in an area where the electrodes are not formed.
The water-resisting quality may be improved by the resin impregnated in the body. However, there is a problem in the above “described structure in that water finds its' way through the edge” of electrode causing deteriorated characteristics.
DISCLOSURE OF THE INVENTION
The present invention aims to present an electronic component with which the passage of water etc. through the electrode edge is prevented by covering the electrode edge with an insulating layer.
An electronic component according to the present invention comprises a body, at least a pair of electrodes formed on the surface of the body at a specified gap, and an insulation layer covering the edge of the electrode and the surface of the body in an area where the electrodes are not formed, wherein at least a part of the insulation layer is formed by impregnating an insulation material into the surface of the body. With the above described structure in which an insulation layer provided on the surface covers the edge of electrodes, peeling-off at the edge of electrode is prevented, at the same time the passage of water through the electrode edge is also avoided.
