摘要：
Provided is a conductive film having excellent conductivity and gas diffusivity that is useful, for example, as a material forming a gas diffusion layer or a catalyst layer of an electrode in a fuel cell. The conductive film includes carbon nanotubes having an average diameter (Av) and a diameter standard deviation (σ) satisfying a relationship 0.60 > (3σ/Av) > 0.20 and a conductive carbon that is different from the carbon nanotubes. A content ratio of the carbon nanotubes relative to the conductive carbon (carbon nanotubes/conductive carbon) is from 1/99 to 99/1 as a mass ratio.
