This release film for green sheet manufacturing has a substrate having a first face and a second face, a smoothing layer provided to the first face of the substrate, and a release agent layer provided to a face of the smoothing layer on a reverse side thereof from the substrate, and is characterized in that the smoothing layer is formed by irradiating, with active energy rays, a smoothing layer formation composition including a thermosetting compound having a mass average molecular weight of 950 or less, and curing the smoothing layer formation composition, the arithmetic mean roughness (Ra1) of an outer surface of the releasing agent layer is 8 nm or less, and the maximum projection height (Rp1) of the outer surface of the releasing agent layer is 50 nm or less. Through the present invention, a release film for green sheet manufacturing can be obtained whereby it is possible to prevent pinholing and the like in the surface of the green sheet, and to manufacture a highly reliable green sheet. |
