Kind Code: A1 The present invention does not contain a silicone-based gas component, has good releasability for various pressure-sensitive adhesives, has a small fluctuation in peeling force, and is low even after being bonded and heated under pressure. Provided is a release agent capable of maintaining a release force. The component (A) has an density of 0.855 g / cc or more and less than 0.868 g / cc, and the component (B) has a density of 0.868 g / cc or more and 0.970 g / cc or less. A release agent containing an ethylene-α-olefin copolymer as a main component, wherein the difference between the average density of the component (A) and the average density of the component (B) is 0.005 g / cc or more, and the component ( A): The compounding ratio (weight ratio) of component (B) is 90:10 to 10:90.
