PROBLEM TO BE SOLVED: To provide: a filler dispersion accelerator capable of uniformity and stably dispersing variety of functional fillers in general-purpose polyolefin resin with a little quantity addition; well-balanced polyolefin resin composition constituted by blending the filler dispersion accelerator, excellent in transparency and mechanical property, enhanced in performance such as rigidity, impact resistance and heat resistance, and excellent in shapability and machinability; and a shaped article obtained with the resin composition.SOLUTION: The polyolefin resin composition can be obtained by dry-blending the general-purpose polyolefin resin and the functional filler and melting and mixing the same by an extruding machine or others, using the filler dispersion accelerator including oxazoline-based aliphatic polymer as a main component including homopolymer of alkenyloxazoline or copomolymer of the alkenyloxazoline and acrylic ester-based and/or acrylamide-based monomer as a main component.
