Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a release film having superior release characteristics, stable release holding when re-bonding and storage, improved blocking characteristics, superior processability, small peeling force with little increase of haze by forming roughened surface on a coating layer.SOLUTION: There is provided a release film including a polyester base film and a silicone release layer. In the release film, the silicone release layer has a thickness of 0.5-5.0 μm and includes an inert particle having a mean diameter of 2-10 μm. In the release film, the silicone release layer contains the addition reaction type silicone resin.
