Abstract

A chip-type ceramic element contains a terminal electrode at each end and an inorganic insulating layer on the surface of the ceramic element between the electrodes. The terminal electrodes include a baked electrode formed from a conductive paste reacted with the material of the inorganic insulating layer. Layers of nickel and tin are plated on the baked electrode for improved heat resistance and soldering adhesion, respectively. The insulating layer prevents unwanted portions of the terminal electrodes from coming into contact with the ceramic element, thereby preventing dispersion in the resistance values of the element.
