Abstract: The ceramic green sheet is formed by molding and drying “a ceramic slurry containing a ceramic powder, an unreacted portion of an isocyanate, an unreacted portion of a polyol, a urethane resin that is produced by mixing isocyanate and polyol and serves as an organic binder, and a solvent”, the ceramic slurry being prepared by mixing the ceramic powder, the isocyanate, the polyol, and the solvent. A thin sheet-like molded body is formed by printing a molded body of a paste, which is prepared by mixing a ceramic powder, an organic binder that is a resin not containing a hydroxyl group, and a solvent, on the ceramic green sheet, and by drying the resultant. A dry shrinkage percentage of the ceramic green sheet upon forming the thin sheet-like molded body thereon can significantly be reduced.

Abstract: In the case where a coating film is formed on a curved outer peripheral surface of a base body from a slurry through a wet process, when pseudoplasticity is imparted to the slurry, the slurry exhibits favorable film formability, and the coating film formed on the curved surface exhibits favorable shape stability. A solid film obtained through solidification of the coating film is formed such that the following relation is satisfied: tedge/tcenter≦1.2 wherein tcenter represents the thickness of the center of the film in a specific direction along the outer peripheral surface, and tedge represents the thickness of the film at a position distant by 2tcenter from one end of the film in the specific direction.
