The invention has an object of providing ethylene/&#x3b1;-olefin copolymers having high randomness and a small number of double bonds in the copolymers. The ethylene/&#x3b1;-olefin copolymers of the invention are obtained by copolymerizing ethylene and an &#x3b1;-olefin having 3 to 20 carbon atoms in the presence of an olefin polymerization catalyst which includes a bridged metallocene compound (A) represented by the formula [I], and at least one compound (B) selected from organometallic compounds (B-1), organoaluminum oxy compounds (B-2) and compounds (B-3) capable of reacting with the bridged metallocene compound (A) to form an ion pair, and have a specific weight average molecular weight, a specific molecular weight distribution, a specific glass transition point and a specific value B.
