PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive film which can be produced without complicated steps, excels in releasability and winding properties, and also excels in adhesion to an adherend. SOLUTION: The pressure-sensitive adhesive film has a pressure-sensitive adhesive layer laminated on one surface of a base material, and the base material has at least two layers of a layer (A) formed of a block copolymer of propylene and ethylene which meets a specific condition (1) or a resin composition containing the block copolymer and a layer (B) formed of a crystalline random copolymer of propylene with ethylene and/or 1-butene, and the layer (A) formed of the block copolymer of ethylene with propylene or the resin composition containing the block copolymer is one surface of the pressure-sensitive adhesive film.
