Ceramic electronic device with inflected external electrodes

A ceramic electronic device includes: a multilayer chip in which dielectric layers are stacked, the multilayer chip having two end faces, an upper face, a lower face and two side faces; a plurality of first internal electrode layers that are provided inside of the multilayer chip, each of the plurality of first internal electrode layers having projection portions extracted to the two side faces; and external electrodes that are provided on the two side faces between the two end faces and are connected to the projection portions, wherein each of the external electrodes has a smaller thickness in a region not connected to the projection portions, has an inflection point toward the projection portions, and has a larger thickness in a region connected to the projection portions, in a direction connecting the two end faces.

Ceramic electronic device with inflected external electrodes and manufacturing method of ceramic electronic device with reverse pattern slurry

Recycled ceramic slurry is produced by a method including the steps: dissolving the waste material of unfired ceramic in a solvent to form a waste solution; and adjusting a composition of the waste solution to thereby produce the recycled ceramic slurry. If the waste material of unfired ceramic includes a metal component, the metal component may be removed therefrom before the step of adjusting the composition of the waste solution.
