PROBLEM TO BE SOLVED: To provide a silicone release polyester film that is used for manufacturing a laminated ceramic capacitor and enables reduction in projections derived from minute silicone aggregates affecting light peeling properties suitable to in particular molding of a thin film ceramic green sheet and surface properties of the green sheet.SOLUTION: A silicone release polyester film includes a coating layer formed by using a release coating composition that includes a water dispersion of an alkenyl group-containing silicone, a water dispersion of silicone having hydrogen atoms directly combined with Si atoms represented by an Si-H group and a crosslinking reaction inhibitor containing an ethynyl group. In the silicone release polyester film, number average molecular weight of the alkenyl group-containing silicone is 10,000-30,000, and content of the crosslinking reaction inhibitor is 50-300 ppm relative to weight of coating liquid used for forming the coating layer. Thickness of the coating layer is 10-100 nm. Silicone aggregates having 400 nm or more of height are not present per 1 mmof the surface of the coating layer. The number of silicone aggregates having 100 nm or more and 400 nm or less of height is 200 pieces/mmor less. |
