PROBLEM TO BE SOLVED: To provide an ion conductive film capable of extending a life of a battery by sufficiently suppressing growth of dendrite without interfering battery performance when used as a battery constituting member.SOLUTION: The ion conductive film is represented by a formula (1) below: (In the formula, T represents a gas permeability rate (s). F represents piercing strength (N). ρ represents density (g/cm). L represents an average film thickness (μm).) An X value is greater than or equal to 200.SELECTED DRAWING: None |
