Abstract
A multilayered ceramic capacitor includes glass melted layers and adhering layers containing conductive patters in which the combination of two or more different species of dielectric materials are used for ceramic layers in the stack of the multilayered capacitor.
Claims14
A multilayered ceramic capacitor comprising in combination:
- (a) a plurality of ceramic thin film pieces;
- (b) joining layers formed on said ceramic thin film pieces in which those are alternatively laminated therein, said ceramic thin film piece having been independently fired, and being sandwiched between two joining layers, said joining layers serving to join the adjacent layers sandwiching said joining layer;
- and
- (c) conductive material layers formed on the surfaces of said ceramic thin pieces for electrodes of said capacitor;
- wherein said plurality of ceramic film pieces comprises two or more species of ceramic films independently different in dielectric properties, each of which species is made of selected dielectric material, each species having at least one film piece laminated in the stack of the layers.
