The invention provides a ceramic green sheet having plasticity, punching property, and sinterability of satisfactory levels as well as a low percent (heat) shrinkage. In the production of a ceramic slurry serving as a raw material of the sheet, ingredients thereof are mixed under such conditions that the functional group ratio (polyol to isocyanate) is 1.5/11.5 to 11.5/11.5; the urethane resin formed from isocyanate and polyol has a repeating-unit-based molecular weight of 290 to 988; and the ratio by weight of the urethane resin to a ceramic powder falls within a range of 4.5 to 10 parts by weight of the urethane resin with respect to 100 parts by weight of the ceramic powder. As a result, a ceramic green sheet having, in well balance, all of the properties (i.e., plasticity, punching property, sinterability, and (heat) shrinkage) required for facilitating subsequent processes such as mechanical working and firing can be provided.
