PROBLEM TO BE SOLVED: To provide a new polyethylene composition of an ultrahigh molecular weight excellent in compactibility, mechanical strength, and heat resistance, and a compact thereof. ! SOLUTION: A polyethylene composition of an ultrahigh molecular weight includes polyethylene (B) of an ultrahigh molecular weight of 5 pts.wt. or more and 900 pts.wt. or less relative to 100 pts.wt. of polyethylene (A) of an ultrahigh molecular weight. The polyethylene (A) has an intrinsic viscosity of 7 dl/g or more and 35 dl/g or less, and a rupture stress (MTS) of 1 MPa or less when fused and drawn at 150°C, while the polyethylene (B) has an intrinsic viscosity of 15 dl/g or more and 60 dl/g or less, and a rupture stress of 2 MPa or more when fused and drawn at 150°C. !
