Abstract
An ethylene-based polymer resin which is obtained by copolymerizing ethylene with an α-olefin having 5 to 20 carbon atoms, and has a melt flow rate (MFR) measured at 190° C. under a load of 21.18 N according to JIS K7210-1995, of not less than 0.01 g/10 min. and less than 1 g/10 min., wherein the melt flow rate and a melt tension(MT) at 190° C. (unit: cN) of the resin satisfy a relation of the following expression (1) and an intrinsic viscosity [η] (unit: dL/g) and the melt flow rate of the resin satisfy a relation of the following expression (2):2×<3.6×  (1)1.02×<[η]<1.50×  (2).
