ABSTRACT:
A highly reliable multilayered electronic element which changes little with temperature in electrostatic capacitance. A multilayered capacitor is made up of a dielectric ceramic body of barium titanate and opposing internal electrodes of nickel which form capacitance. Nickel diffuses over a controlled distance (L.sub.2) which is 3-30% of the interval (L.sub.1) between the internal electrodes. The distance of diffusion varies depending on the conditions of firing (such as temperature, duration, and atmosphere).
