A film contains at least one macromolecular compound selected from the group consisting of resins and rubbers and an electrically conductive filler including at least a needle-shaped filler and dispersed in the macromolecular compound. The content of the electrically conductive filler is 40% by volume or more.

A polymer film includes at least one type of polymer selected from the group consisting of a resin and rubber and fillers dispersed in the polymer; in which in a case where the polymer film is three-dimensionally analyzed with FIB-SEM, a film thickness of the polymer film is denoted by Tm, and a length of the filler in a film thickness direction of the polymer film is denoted by Lf, a proportion of the number of fillers having Lf/Tm of 0.01 or more and less than 1.0 to the number of all the fillers is more than 40% and less than 100%.
