PROBLEM TO BE SOLVED: To provide an injection-molded body of an ethylene homopolymer or a copolymer of ethylene and an α-olefin having excellent fluidity and producing thin-wall injection-molded bodies high in rigidity and high in impact resistance. SOLUTION: The polyethylene injection-molded body is made of an ethylene homopolymer or a copolymer of ethylene and an α-olefin having 3-20 carbon atoms, characterized in that it has (A) a melt index(MI) of 30-150 g/10 minutes at 190 deg.C under a 2.16 kg load, (b) a density of 0.950 g/cm3 or more, and (C) a relationship of -31.7×Ln(MI)+183<VI<-31.7×Ln(MI)+213 between the melt viscosity VI(Pa.s) determined under conditions of 190 deg.C and a shear rate of 2670 sec-1. |
