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 <requirement (1)> and <requirement (2)>: <Requirement (1)> 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 α Rα: abundance (%) of low-mobility component α Tβ: relaxation time (ms) of intermediate component β Rβ: abundance (%) of intermediate component β <Requirement (2)> An intermediate component ratio at 180° C. determined by (formula II) is 0.25 to 0.5: (intermediate component ratio)=Rβ/(Rα+Rβ) (formula II).
