PROBLEM TO BE SOLVED: To provide an olefin polymer having high activity without using a large amount of aluminoxane, high quality, and having a small amount of residual metal, which can be industrially advantageously obtained efficiently. Provide a production catalyst. SOLUTION: (a) a transition metal compound of Groups 8 to 10 of the periodic table, (b) a clay, a clay mineral or an ion-exchangeable layered compound, (c) a silane compound, and (d) an organoaluminum compound and / or ( e) An olefin polymer production catalyst containing an alkylating agent. |
