A polypropylene film exhibits a high breakdown voltage even in a high temperature environment and can exhibit a voltage resistance and reliability even in a high temperature environment when used as a capacitor, and a metal layer laminated film and a film capacitor using the polypropylene film. For the polypropylene film, at least one surface of the film has an elastic modulus of 2.6 GPa or more, measured by nanoindentation measurement, and the sum of heat shrinkage rates is in the film longitudinal and width directions 5% or less in a heat treatment at 130° C. for ten minutes.
