Abstract
A ceramic electronic device includes a plurality of dielectric layers of which a main component is a ceramic having a perovskite structure, and a plurality of internal electrode layers, each of which is stacked through each of the plurality of dielectric layers and includes a co-material which is inactive against the main component of the plurality of dielectric layers.
Claims15
A ceramic electronic device comprising:
- a plurality of dielectric layers of which a main component is a ceramic having a perovskite structure;
- and
- a plurality of internal electrode layers, each of which is alternatively stacked with each of the plurality of dielectric layers and includes metal crystal grains, and a co-material which is inactive against the main component of the plurality of dielectric layers, without including a ceramic having a same composition as the ceramic of the main component of the plurality of dielectric layers.
A manufacturing method of a ceramic electronic device comprising:
- forming a multilayer structure by stacking a plurality of stack units, each of which has a structure in which a pattern of metal conductive paste including a co-material is printed on a dielectric green sheet of a dielectric material including ceramic material powder having a perovskite structure, the pattern of metal conductive paste including metal powder and the co-material without including ceramic material powder having a same composition as the ceramic material powder included in the dielectric material;
- and
- firing the multilayer structure,
- wherein the co-material does not react with the ceramic material powder at a temperature of the firing of the multilayer structure.
