Monolithic ceramic electronic device and method of manufacturing same

摘要

A method of manufacturing a monolithic ceramic electronic device includes the following steps: forming a first metal film (12) on a PET film (11); forming a multilayered metal film (17) by forming a second metal film (14) on a part of the first metal film, the second metal film being thicker than the first metal film; forming a monolithic ceramic structure (18) including the multilayered metal film (17); forming a portion of the first metal film (12), which is overlain by the second metal film (14) in the monolithic ceramic structure, into an insulating structure in such a manner that metal components forming the part are diffused into ceramics (16); and firing the ceramics. Disclosed also is a monolithic ceramic electronic device manufactured by the method. As a result, a stepped portion between a portion in which the internal electrodes overlap one another and a portion in which the internal electrodes do not overlap can be prevented from being formed, generation of delamination can effectively be prevented, whereby a monolithic ceramic electronic device exhibiting stable characteristics and a method for manufacturing the monolithic ceramic electronic device can be obtained.
