PROBLEM TO BE SOLVED: To provide a mold releasing film enabling effective manufacture of a ceramic green sheet, a not more than 3μm thick ceramic green sheet in particular and showing excellent adhesion between a base film and the mold releasing film even without an anchor coat layer. SOLUTION: The mold releasing film has a silicone-based resin film on at least one surface of the base film, and the film contains a silicone compound obtained by reacting a silicone oil having a hydroxyl group with an isocyanate compound represented by formula (1) wherein n is an integer of 1 to 3, and R is an alkyl group or an ester group and/or a ketone group and/or an alkyl group having a hydroxyl group or an aralkyl group or an alkenyl group. The mold releasing film satisfies peeling strength of 0.1 to 8 g/50 mm and remaining adhesion of not less than 80%. COPYRIGHT: (C)2006,JPO&NCIPI
