Abstract: Provided is a polyethylene fiber having outstanding anti-creep characteristics while having high strength. The present invention provides an ultra-high molecular weight polyethylene fiber including ethyl branches as side chains, characterized in that the ratio {(C2H5/1000C)/(elongation stress)} of the number of ethyl branches per 1,000 carbon atoms (C2H5/1000C) to the elongation stress of the polyethylene fiber (MPa) is 2 to 30 branches/1,000 carbon atoms/MPa.
