Method of making a ceramic capacitor

Claim 1

A process of making a ceramic capacitor, said process comprising the steps of: forming a plurality of first and second inner electrodes on one surface of an elongated ceramic green sheet having first and second generally parallel longitudinal side edges, said first and second electrodes being alternately arranged in the longitudinal direction of said ceramic green sheet, an insulating gap of size g, being located between each adjacent electrode, said ceramic green sheet having a thickness t, each of said first inner electrodes being formed with one side edge thereof extending to said first side edge of said ceramic green sheet and another side edge thereof extending towards, but being spaced from, said second side edge of said ceramic green sheet, each of said second inner electrodes being formed with one side edge thereof extending to said second side edge of said ceramic green ceramic sheet and another side edge thereof extending toward, but being spaced from, said first side edge of said ceramic green sheet; rolling said ceramic green sheet into a multilayered cylindrical body of inner diameter d, said rolling step causing an elongation of said ceramic green sheet, said rolling step being formed in such a manner that each first inner electrode overlaps a respective second inner electrode, said ceramic green sheet being interposed therebetween, the length Ln of each successive electrode being equal to: Ln=[d+(2n-1)t]πk-g wherein n is the number of turns of the rolled ceramic green sheet, and k is a correction factor which compensates for the elongation of said sheet during the rolling step; forming first and second outer electrodes at respective locations on the surface of said cylindrical body, said plurality of first and second inner electrodes being electrically connected to said first and second outer electrodes, respectively.
