PROBLEM TO BE SOLVED: To provide a self-adhesive biaxially oriented polypropylene film having high adhesiveness, easy peeling property, free of problems such as a glue residue or migration of a silicone release agent, and thereby, useful for a protective film of electric or electronic components or the like.SOLUTION: A resin composition layer (A) containing polypropylene and a polypropylene elastomer is disposed on one surface layer (adhesive layer), and a polypropylene resin layer (B) is used as a core layer. A biaxially oriented polypropylene film has a configuration of the layer (A)/the layer (B)/the layer (B) comprising two types of layers in three layers, or a configuration of the layer (A)/the layer (B) comprising two types of layers in two layers. A compounded amount of the polypropylene elastomer in the resin composition layer (A) is 60 mass% or more. |
