Provided are a resin film wherein film deformation is further suppressed, and a resin film forming method. The resin film is a long resin film (11) that has an embossed section (13A) at least on the both side end sections along the longitudinal direction. The cross-section of the embossed section (13A) in a direction orthogonally intersecting with the longitudinal direction has a pair of protruding sections (13b, 13b) and a recessed section that is provided between the pair of protruding sections (13b, 13b) on the surface (14b) of the resin film (11) on the opposite side from the surface (14a) whereupon the pair of protruding sections (13a, 13b) are formed. |
