Provided is a biaxially-stretched film wherein the biaxial stretching is possible in a broader temperature range and which is excellent in thickness accuracy, and an ethylene polymer composition serving as a raw material of the film. The biaxially-stretched film of the present invention is obtained from an ethylene polymer composition (E) including a specific ethylene polymer component (A) containing 20 to 100 wt % of an ethylene polymer (a) being a copolymer of ethylene and a C4-10 &#x3b1;-olefin and having specific melt flow rate and density, and an ethylene polymer component (B) being another copolymer of ethylene and a C4-10 &#x3b1;-olefin, wherein a weight fraction [W] of the ethylene polymer component (A) is 0.50 or more and 0.92 or less, and a weight fraction [W] of the ethylene polymer component (B) is 0.08 or more and 0.50 or less provided that Wand Wtotal 1.0.
