An ethylene-based polymer which is a copolymer obtained from ethylene and a C3 to C10&#x3b1;-olefin and satisfies the following requirements (i), (ii), (iii) and (iv) simultaneously provides a blow-molded product and an extrusion-molded product excellent in moldability, mechanical strength and outward appearance. The ethylene-based polymer of the invention is preferably produced by copolymerizing ethylene with a C3 to C10 &#x3b1;-olefin, in the presence of a solid catalyst carrying, on (C) a solid carrier, a mixed transition metal compound consisting of (A1) a group 4 transition metal compound containing a specific salicyl aldimine ligand and (A2) a group 4 transition metal compound containing a specific cyclopentadienyl ligand and (B) at least one compound selected from (b-1) an organometallic compound, (b-2) an organoaluminum oxy compound, and (b-3) a compound reacting with the transition metal compound to form an ion pair.
