PROBLEM TO BE SOLVED: To provide an olefin polymerization catalyst capable of obtaining a polymer having no or little branching and a high molecular weight, a polymer having good particle properties, and a wide molecular weight distribution and moldability. To provide an olefin polymerization method capable of producing an excellent polymer. An olefin polymerization catalyst comprising the following components (A) and (B) and an optional component (C). Component (A): transition metal compound represented by the following general formula [1] (Where A and A ′ are coordinated with M, periodic table 15 to 16) A ligand having a group atom, Q is a bonding group having an lone bond or a π bond capable of coordinating with M, and bridging A and A ′ at any position, and M is a periodic table 8, 9 Group metal atom, X is a hydrogen atom, a halogen atom, a hydrocarbon group, an oxygen-containing hydrocarbon group, a nitrogen-containing hydrocarbon group, a halogen-containing hydrocarbon group, n represents the valence of the central metal M. Component (B): One or more substances selected from ion-exchange layered compounds other than silicates or inorganic silicates Optional component (C): Organoaluminum compound |
