Abstract
Provided are a film including a layer A, and a layer B provided on at least one surface of the layer A, in which an elastic modulus of the layer A at 160° C. is 100 MPa to 2,500 MPa, and a value of a difference LA−LB between a value LA obtained by subtracting a weight residual rate of the layer A at 900° C. from a weight residual rate of the layer A at 440° C. and a value LB obtained by subtracting a weight residual rate of the layer B at 900° C. from a weight residual rate of the layer B at 440° C. is 80% or less.
