Claim:
A photosensitive film which comprises a support film (A), a photosensitive resin composition-containing photosensitive resin layer (B) formed on said support film (A), and a protecting film (C) stuck onto said photosensitive resin layer (B), wherein: the number of fish eyes having a diameter of at least 80 μm included in said protecting film (C) does not exceed 5 fish eyes/m 2 when measured under a microscope at a multiplication of 100; and said photosensitive resin composition-containing photosensitive resin layer (B) has a film thickness of 5 to 30 μm, and whereby generation of air voids between the photosensitive layer (B) and a substrate after lamination of the photosensitive film on the substrate while removing the protecting film (C) from the photosensitive film is reduced.
