Zusammenfassung:	A polyethylene powder, wherein, when a free induction decay curve obtained by the Carr-Purcell-Meiboom-Gill method in pulsed NMR is subjected to three-component approximation, the relaxation time T of each component and the abundance R of each component satisfy the following and :An entanglement index at 180° C. determined by (formula I) is 12 to 25 ms:(entanglement index)=Tα×Rα/(Rα+Rβ)+Tβ×Rβ/(Rα+Rβ) (formula I)Tα: relaxation time (ms) of low-mobility component αRα: abundance (%) of low-mobility component αTβ: relaxation time (ms) of intermediate component βRβ: abundance (%) of intermediate component βAn intermediate component ratio at 180° C. determined by (formula II) is 0.25 to 0.5:(intermediate component ratio)=Rβ/(Rα+Rβ) (formula II).
