Abstract
To provide a film that prevents the film itself from being broken when peeled off and prevents its surface from becoming rough and a method for producing the same, and a laminate including the film.SOLUTION: A film has a dielectric loss tangent of 0.01 or less, with its surface free energy on at least one surface being 15 mN / m-36 mN / m. Additionally, the film has a dielectric loss tangent of 0.01 or less, in which the surface coverage of at least one surface with at least one compound selected from the group consisting of a fluorine atom-containing compound and a silicon atom-containing compound is 30%-100%. There are also provided methods for producing the films. There are also provided laminates including the films.SELECTED DRAWING: None
