PURPOSE:To improve accuracy, and to control an electrostatic-capacitance temperature coefficient by properly combining two kinds or more of dielectric ceramic baked sheets having different dielectric characteristics, bringing the sheets into a multilayer state and lap-joining the sheets. CONSTITUTION:Two kinds of dielectric ceramic materials having different dielectric characteristics are used as dielectric layers, and it is preferable that one of the materials has the temperature coefficient of positive electrostatic capacitance and the other has the temperature coefficient of negative electrostatic capacitance. At least one of each of two kinds or more of dielectric ceramic sheets, which are previously baked discretely and have different dielectric characteristics, is employed as the dielectric layers 1, 2, and conductor layer patterns 3 and glass material paste layers 4 are shaped onto the respectively baked dielectric ceramic sheets through a thick-film screen printing method. A large number of ceramic sheet layers formed in this manner are superposed, baked ceramic sheets 5 are stacked onto the uppermost surface and lowermost surface of the laminate, the structure is thermally treated and joined at a comparatively low temperature, a laminate obtained is cut into a specified size, and terminal electrodes are provided to each laminate, thus manufacturing a laminated ceramic capacitor. |
