A release film 1 for a ceramic slab manufacturing process, comprising a substrate 11 and a release agent layer 12 provided on one side of the substrate 11, wherein the release agent layer 12 is an active energy ray-curable component and an oxime component The cured product of the agent composition, the arithmetic mean roughness (Ra) of the surface of the release agent layer 12 on the side opposite to the substrate 11 is 8 nm or less, and the maximum protrusion height (Rp) is 50 nm or less, and the release agent layer 12 is made of Nai. The modulus of elasticity measured by the rice indentation test is 4.0 GPa or more, and the arithmetic mean roughness (Ra) of the surface of the substrate 11 opposite to the release agent layer 12 is 5 to 50 nm, and the maximum protrusion height (Rp) is 30~500nm. For example, according to the peeling film 1 for ceramic green sheet manufacturing engineering, it can be prevented. It is suppressed that the ceramic green sheet has defects such as pinholes or thickness unevenness, and the peeling property of the ceramic green sheet is also excellent. |
