A laminated film includes a substrate film and layer A provided at least on one side thereof, layer A containing (1) a (poly)caprolactone segment and (2) a urethane bond, wherein a distilled water contact angle on layer A and a diiodomethane contact angle on layer A are 95° or more, but less than 120° and 70° or more, but less than 87°, respectively. 1. A laminated film comprising a substrate film and layer A provided at least on one side thereof , layer A containing (1) a (poly)caprolactone segment and (2) a urethane bond , wherein a distilled water contact angle on layer A and a diiodomethane contact angle on layer A are 95° or more , but less than 120° and 70° or more but less than 87° , respectively.2. The film as described in claim 1 , wherein the diiodomethane contact angle on layer A is 80° or more but less than 87°.3. The film as described in claim 1 , wherein layer A further comprises (3) a polysiloxane segment and/or polydimethyl siloxane segment.4. The film as described in claim 1 , wherein fluorine atoms account for 0.4% to 50% of the total number (100%) of fluorine atoms claim 1 , carbon atoms claim 1 , nitrogen atoms claim 1 , oxygen atoms claim 1 , and silicon atoms as detected on a layer A-side surface of the laminated film via X-ray photoelectron spectroscopy.5. The film as described in satisfying relationship a/b is 0% to 60% claim 1 , wherein “a” is a maximum value of fluorine atom detection intensity measurements obtained by TOF-SIMS over a thickness range of 1% to 100% as measured from a layer A-side surface towards the substrate film as a proportion to the entire 100% thickness of the layer claim 1 , and “b” is a maximum value of fluorine atom detection intensity measurements obtained by TOF-SIMS over a thickness range of 0% to 1% claim 1 , exclusive claim 1 , as measured from the layer A-side surface towards the substrate film.6. The film as described in claim 5 , wherein proportion a/b is 5% to 20%.7. The film as described in claim 1 , ...
