Abstract: A photosensitive film of the present invention includes a carrier film having a first surface whose surface roughness is 0.1 to 0.4 μm, and a photosensitive layer formed on the first surface, in which a haze of the carrier film is 30 to 65%, and a spectral haze at a wavelength of 405 nm of the carrier film, as measured by providing a transparent resin layer in which a difference between a refractive index of the transparent resin layer and a refractive index of the photosensitive layer is within ±0.02 on the first surface, is 0.1 to 9.0%.
