Abstract
A release film comprises a base material and a release agent layer provided at one side of the base material. The release agent layer comprises a cured material of a release agent composition. The release agent composition contains an active energy ray curable component and a silicone-based component. A surface of the release agent layer at the opposite side to the base material has an arithmetic average roughness (Ra) of 8 nm or less and a maximum projection height (Rp) of 50 nm or less. An elastic modulus measured by a nanoindentation test of the release agent layer is 4.0 GPa or more. A surface of the base material at the opposite side to the release agent layer has an arithmetic average roughness (Ra) of 5 to 50 nm and a maximum projection height (Rp) of 30 to 500 nm.
