Release film for producing green sheet

A release film for producing a green sheet, the release film comprising:

• a base material having a first surface and a second surface;
• a release agent layer provided at a side of the first surface of the base material, wherein the release agent layer is formed by irradiating an active energy ray to a coated layer and curing the coated layer, wherein the coated layer is formed by coating a release-agent-layer-forming material on the side of the first surface of the base material, and wherein the release-agent-layer-forming material includes an active energy ray curable compound (a1) and a polyorganosiloxane (b1);
• and
• a back coat layer provided at a side of the second surface of the base material, wherein the back coat layer is formed by irradiating the active energy ray to a coated layer and curing the coated layer, wherein the coated layer is formed by coating a back-coat-layer-forming material on the side of the second surface of the base material, and wherein the back-coat-layer-forming material includes an active energy ray curable compound (a2),
• wherein an arithmetic average roughness of an outer surface of the release agent layer is 8 nm or less and a maximum projection height of the outer surface of the release agent layer is 50 nm or less, and
• wherein an arithmetic average roughness of an outer surface of the back coat layer is in the range of 5 to 40 nm and a maximum projection height of the outer surface of the back coat layer is in the range of 60 to 500 nm.
