摘要： At least one conductive layer is formed by applying paste mainly containing metal on at least one insulating sheet. At least one sintered body is provided by firing the at least one insulating sheet having the at least one conductive layer formed thereon. The amount of the metal contained in the at least one conductive layer of the at least one sintered body is detected. A sintered body is selected from the at least one sintered body based on the detected amount of the metal. An outer electrode is formed on the selected sintered body, thus providing a ceramic electronic device. This method allows a defective to be detected in an early stage of manufacturing processes, hence providing a ceramic electronic device to be manufactured efficiently.

摘要： A solid electrolytic capacitor is obtained in which a sintered metal serves as an anode and a silver layer serves as a cathode. A surface of sintered metal made of tantalum or the like and having an open porosity ratio of more than 75% is oxidized so that an oxide film made of tantalum pentoxide or the like is deposited thereon. Cavities of the metal are filled with an electrically conductive material. Then, the metal is wound around a lead wire and made into a desired shape and size. The silver layer is formed on this porous metal body. Because a specific surface area of the sintered metal is large, a large capacity is obtained.

摘要： A method of manufacturing a multilayer ceramic capacitor includes the steps of: preparing a mixture of a raw material powder mainly composed of barium titanate particles; forming the mixture and a binder into a green sheet; alternately layering the green sheet and an internal electrode to obtain a laminated body; and sintering the laminated body. The step of preparing the mixture includes the steps of: introducing the raw material powder and the dispersion medium into a mixing container, and stirring them with balls serving as a mixing medium, to obtain a slurry containing a raw material powder mixture; and drying the slurry. The mixing medium has a diameter that is equal to or less than 400 times the mean particle size of the barium titanate particles of the raw material. The present invention provides a multilayer ceramic capacitor having good DC bias characteristics by suppressing the variation in crystal particles.
