Abstract
A cellulose fiber-reinforced polyolefin resin composition contains a polyolefin resin, a cellulose fiber having a fiber length of 1 μm or more, an acid-modified elastomer, and high-density polyethylene. In the composition, an amount of the cellulose fiber is 6 to 95 parts by mass relative to 100 parts by mass of the polyolefin resin, an amount of the acid-modified elastomer is 0.5 to 1.2 times by mass the amount of the cellulose fiber; and, an amount of the high-density polyethylene is 15 to 55 parts by mass relative to 100 parts by mass of the polyolefin resin.
