Zusammenfassung:	The present invention provides an adhesive film hardly suffering from fisheyes and having excellent mechanical strength and heat resistance as well as good adhesion properties, which can be suitably used as various surface protective films, etc. The present invention relates to an adhesive film comprising a polyester film and an adhesive layer formed on at least one surface of the polyester film, in which the adhesive layer comprises a (meth)acrylic resin comprising a (meth)acrylate unit that comprises an alkyl group having not less than 4 carbon atoms at an ester end thereof, a content of the (meth)acrylate unit in the (meth)acrylic resin being not less than 20% by weight; and an adhesion strength to a polymethyl methacrylate plate of the adhesive layer is not less than 1 mN/cm.
