Abstract
A manufacturing method of ceramic slurry being used for producing a green sheet which can have a smooth surface, exhibits a satisfactory sheet strength, and is excellent in workability such as releasing, a green sheet produced by the use of the slurry produced by the method, and a multilayer ceramic device produced by the use of the green sheet is provided. According to the present invention, a manufacturing method of ceramic slurry at least comprising a ceramic powder and a binder resin solution, wherein a high-pressure dispersing treatment of the ceramic powder and a lacquer for preliminary addition, which is a part of the binder resin solution, is carried out so that a shearing rate is set to 1×107 to 1×108 [1/sec] to prepare a preliminary slurry, and at least a lacquer for post-addition, which a high-pressure dispersing treatment is not applied, is added to the preliminary slurry which a high-pressure dispersing treatment is applied.
