Provided is a film including a phase-separated structure having at least two phases, in which in a case where a glass transition temperature of a first phase, which is one of the at least two phases, is denoted by Tg1, a second phase which is one of the at least two phases and is different from the first phase does not have an inflection point of a storage elastic modulus in a temperature range of 25° C. or higher and the Tg1 or lower.
