Abstract: A catalyst configured to be handled more easily than conventional catalysts and configured to copolymerize an ?-olefin and a (meth)acrylic acid ester with high activity. The objects are achieved by polymerization using an olefin polymerization catalyst which contains a metal complex obtained by reacting a ligand having a specific structure and a transition metal compound containing a transition metal selected from nickel or palladium having a specific structure.
