Disclosed is a stretched resin film having a water-absorbent layer on at least one surface thereof, wherein: said water-absorbent layer includes 24-64 mass% of a thermoplastic resin, 35-75 mass% of inorganic fine powder, and 1-2 mass% of a hydrophilization agent for said inorganic fine powder; the liquid absorption capacity of said water-absorbent layer is 0.5 ml/m2 or greater; and the liquid absorption coefficient calculated according to the same method is 0.1-2 ml/(m2·ms1/2). This stretched resin film is a film substrate wherein, when the surface of the film substrate is coated with a coating material, the film substrate absorbs a portion of the coating material without creating bubbles, thus providing a uniform coating appearance. |
