A polyethylene composition comprising: the following features and: a cumulative percentage elution from 50°C to 98°C is 50% by mass or more and less than 80% by mass in an elution temperature-cumulative eluate volume curve obtained by measuring eluate volumes every 1°C by temperature rising elution fractionation (TREF) of cross-fractionation chromatography; and the polyethylene composition comprises at least one eluted component having a weight-average molecular weight (M w) of 200,000 or more at a temperature of 85°C or more and less than 105°C among eluted components recovered every 1°C by temperature rising elution fractionation (TREF) of cross-fractionation chromatography, wherein a difference between a resin temperature at which a peak of the largest torque is detected and a resin temperature at which a peak of the second largest torque is detected is 25°C or less in a torque curve obtained by kneading 24 g of liquid paraffin having an average molecular weight of 450 or more and less than 550 using Labo Plastomill under conditions of a set temperature of 114°C and a rotational speed of 5 rpm for 10 minutes, then adding thereto 16 g of the polyethylene composition and 0.4 g of tetrakis[methylene(3,5-di-t-butyl-4-hydroxy-hydrocinnamate)]methane, and kneading the mixture at a rotational speed of 30 rpm for 3 minutes, followed by kneading under conditions of elevating the set temperature from 114°C to 163°C over 6 minutes. the following features and: a cumulative percentage elution from 50°C to 98°C is 50% by mass or more and less than 80% by mass in an elution temperature-cumulative eluate volume curve obtained by measuring eluate volumes every 1°C by temperature rising elution fractionation (TREF) of cross-fractionation chromatography; and the polyethylene composition comprises at least one eluted component having a weight-average molecular weight (M w) of 200,000 or more at a temperature of 85°C or more and less than 105°C among eluted components recovered every 1°C by temperature rising elution fractionation (TREF) of cross-fractionation chromatography, a cumulative percentage elution from 50°C to 98°C is 50% by mass or more and less than 80% by mass in an elution temperature-cumulative eluate volume curve obtained by measuring eluate volumes every 1°C by temperature rising elution fractionation (TREF) of cross-fractionation chromatography; and the polyethylene composition comprises at least one eluted component having a weight-average molecular weight (M w) of 200,000 or more at a temperature of 85°C or more and less than 105°C among eluted components recovered every 1°C by temperature rising elution fractionation (TREF) of cross-fractionation chromatography, wherein a difference between a resin temperature at which a peak of the largest torque is detected and a resin temperature at which a peak of the second largest torque is detected is 25°C or less in a torque curve obtained by kneading 24 g of liquid paraffin having an average molecular weight of 450 or more and less than 550 using Labo Plastomill under conditions of a set temperature of 114°C and a rotational speed of 5 rpm for 10 minutes, then adding thereto 16 g of the polyethylene composition and 0.4 g of tetrakis[methylene(3,5-di-t-butyl-4-hydroxy-hydrocinnamate)]methane, and kneading the mixture at a rotational speed of 30 rpm for 3 minutes, followed by kneading under conditions of elevating the set temperature from 114°C to 163°C over 6 minutes.
