Abstract: The present invention provides a mold release film including a resin layer provided on one surface of a polyester film, wherein the resin layer includes an acid-modified polyolefin resin with a proportion of an acid-modifying component of 1 to 10% by mass, polyvinyl alcohol and a cross-linking agent; the content of polyvinyl alcohol exceeds 200 parts by mass and is 1000 parts by mass or less, and the content of the cross-linking agent is 1 to 20 parts by mass in relation to 100 parts by mass of the acid-modified polyolefin resin; and the peel force between the resin layer and a rubber-based adherend measured by bonding the rubber-based adherend to the resin layer is 0.5 N/cm or less.
