PROBLEM TO BE SOLVED: To provide a release film for molding a ceramic green sheet, which has excellent peelability and is less likely to cause damage such as pinhole defects and cracks at the time of peeling to an ultrathin ceramic green sheet to be molded. SOLUTION: This is a release film in which a release layer of 0.2 to 3.5 μm is laminated directly on at least one surface of a polyester film or via another layer, and the region surface roughness of the surface of the release layer. (Sa) is 5 to 40 nm, the maximum mountain height (Rp) is 60 nm or less, the static friction coefficient of the release layer surface of the release layer film is 0.05 or more and 2.00 or less, and the dynamic friction coefficient is 1. A release film for manufacturing ceramic green sheets, which is 0.00 or less. [Selection diagram] None |
