Abstract
It is an object of the present invention to provide a method for manufacturing a multi-layered unit for a multi-layered ceramic electronic component which can reliably prevent short circuit failure from occurring in a multi-layered ceramic electronic component and form an electrode layer in a desired manner.A method for manufacturing a multi-layered ceramic electronic component includes a step of printing a conductive paste containing a binder containing ethyl cellulose having a weight average molecular weight of MWL and ethyl cellulose having a weight average molecular weight of MWH at a weight ratio of X:(1−X), where MWL, MWH and X are selected so that X*MWL+(1−X)*MWH falls within a range of 145,000 to 215,000 and at least one solvent selected from the group consisting of isobornyl acetate, dihydroterpinyl methyl ether, terpinyl methyl ether, α-terpinyl acetate, I-dihydrocarvyl acetate, I-menthone, I-menthyl acetate, I-perillyl acetate and I-carvyl acetate on a ceramic green sheet containing a butyral system resin as a binder in a predetermined pattern, thereby forming an electrode layer.
