Abstract
Abstract Disclosed is a method of manufacturing a ceramic laminate which is adapted to manufacture a laminated ceramic capacitor, for example. This method comprises the steps of stacking a plurality of ceramic green sheets (41) containing ceramic powder and a first binder on a base and forming a metal paste film (42) containing metal powder and a second binder for providing an internal electrode on an upper major surface of a prescribed one of the ceramic green sheets (41) during the stacking step. In such a method, a junction member (47) containing a solvent which can commonly dissolve the first and second binders is prepared in order to join the plurality of ceramic green sheets with no application of pressure, to be applied between adjacent pairs of the plurality of ceramic green sheets (41), which are stacked with each other. The junction member (47) joins the adjacent pairs of ceramic green sheets with each other through chemical function.
