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.
