Abstract:
1. A production method of a multilayer electronic device, comprising the steps of: forming a lower side green sheet having a thickness of 1 μm or less including at least a ceramic powder and a binder of a curable resin on a supporting body; curing said curable resin included in said lower side green sheet; forming a first electrode pattern layer on a surface of said lower side green sheet; forming an intermediate green sheet having a thickness of 1 μm or less including a binder of a curable resin on the electrode pattern layer after forming said electrode pattern layer on said lower side green sheet; curing the curable resin in said intermediate green sheet; and forming a second electrode pattern layer on said intermediate green sheet; wherein: two or more said electrode pattern layers are formed on said supporting body via one or more said intermediate green sheet; an upper side green sheet including a binder of a curable resin is formed on a topmost electrode pattern layer among the two or more electrode pattern layers; a multilayer unit composed of single said lower side green sheet, one or more said intermediate green sheet, two or more said electrode pattern layers and said upper side green sheet is formed on said supporting body; without curing the curable resin in said upper side green sheet, two or more said multilayer units released from said supporting body are stacked, so that said lower side green sheet in one multilayer unit contacts said upper side green sheet of another multilayer unit, to form a green chin and, then, said green chip is fired; and the thickness of the intermediate green sheet is approximately equal to the sum of the thickness of the lower side green sheet and a thickness of the upper side green sheet.
