An adhesive agent comprising a condensation resin having a structural unit obtained by polycondensing a polymerizable monomer containing a monomer (A) having 2 or more carboxyl groups and a monomer (B) having 2 or more amino groups, and meeting at least one of the following (1) and (2):

Adhesive agent, adhesive material using the same, and method of use thereof

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&#xb0; C. to 120&#xb0; 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&#xb0; C. and 60 MPa to 120 MPa under an atmosphere at 120&#xb0; C. and an adhesive film containing it as the carrier.
