An ethylene/&agr;-olefin copolymer having a density of 0.900 to 0.965 g/cm ; having an MI of 0.01 to 100 g/10 minutes; in a chromatogram with the use of Rayleigh ratio obtained by extrapolating GPC-MALLS data at a scattering angle of 0&deg;, showing an average {overscore (Mc)} obtained by measuring five times of 0.5% or more and a standard deviation <&sgr;> from the average of 35% or less, wherein Mc stands for the chromatographic area ratio of the components having molecular weight of 1,000,000 or more calculated on the basis of the above measurement; and having a W30 (weight fraction of the portion eluted below 30&deg; C.) in CFC measurement of 1 (% by weight) or less; and a film thereof.
