    • PROBLEM TO BE SOLVED: To provide a modified polyolefin resin having excellent adhesion property relative to a hardly adhesive base material and being excellent in moldability while maintaining flowability of the material as much as possible, and its manufacturing method.
      SOLUTION: The co-rotation biaxial extruder has a screw having a constitution having at least one of at least one kneading zone and a pressure retaining zone for damming or reversely feeding a resin mixture. The manufacturing method for the modified polyolefin resin composition is characterized in that a radical polymerization initiator (B) is melted/kneaded relative to the polyolefin resin (A) to plasticize it and an epoxy group-containing vinyl monomer (C-1) and an aromatic vinyl monomer (C-2) or further a (meth)acrylate monomer (C-3) are melted/kneaded to obtain it.
