Laminated ceramic electronic component and method for manufacturing same
First Claim
1. A method for manufacturing a laminated ceramic electronic component, comprising the steps of:
- forming composite sheets, each having a conductor portion and a ceramic layer portion, on a carrier film;
laminating the composite sheets with each other and separating each of the composite sheets from the carrier film to obtain a first laminated body;
cutting the first laminated body in a thickness direction thereof so as to divide the conductor portions to obtain at least one second laminated body having the conductor portions exposed on one of the cut surfaces; and
firing the at least one second laminated body to obtain a sintered ceramic body having an external electrode formed of the exposed conductor portions.

Abstract
A laminated ceramic electronic component significantly simplifies a step of forming external electrodes and has reliable electrical connection between an internal electrode and the external electrodes. A method for manufacturing the laminated ceramic electronic component includes the steps of forming composite sheets each having a conductor and a ceramic layer provided at the sides of the conductor on a carrier film, laminating the composite sheets with each other for forming a mother laminate, cutting the mother laminate in the thickness direction thereof so as to divide the conductor for forming laminates each forming one laminated ceramic electronic component, in which the conductor is exposed on the cut surface of the laminate, and firing the laminate so as to simultaneously form external electrodes from the exposed conductors and a sintered ceramic body.
