An ethylene/C4-10 alpha-olefin copolymer which is reduced in neck-in in T-die molding and is excellent in suitability for high- speed film formation and mechanical strength. The polymer is obtained through polymerization in the presence of an olefin polymerization catalyst which comprises a solid support and, deposited thereon, (A) a solid transition metal catalyst component obtained through contacting from (a) a compound of a Group 4 transition metal of the Periodic Table containing one or more ligands having a cyclopentadienyl skeleton, (b) an organic aluminumoxy compound, and (c) a polyfunctional organic halide and optionally from (d) an organoaluminum compound, and which optionally contains (B) an organoaluminum compound.
