An object of the present invention is to provide a polypropylene polymer film superior in convenience in handling that does not generate troubles such as wrinkling, elongation or breakage during processing at a high temperature of 80° C. to 120° C., independently of the conveying method used in the drying step, and an adhesive film having the polypropylene polymer film as its carrier. Provided are a polypropylene polymer film, characterized by having a tensile modulus of 300 MPa to 1,000 MPa under an atmosphere at 23° C. and 60 MPa to 120 MPa under an atmosphere at 120° C. and an adhesive film containing it as the carrier.
