The invention has an object to provide a catalyst for polymerizing or copolymerizing an ±-olefin, catalyst constituent thereof, and method of polymerizing ±-olefins with the catalyst, for production of ±-olefin polymers or copolymers with high hydrogen response, high polymarization reaction rate, high stereoregularity and excellent melt fluidity. The invention discloses a catalyst constituent of the catalyst for polymerizing or copolymerizing an ±-olefin, represented by Formula 37 or 38: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Formula 37€ƒ€ƒ€ƒ€ƒ€ƒSi(OR 1 ) 3 (NR 2 R 3 ) (where in Formula 37 , R 1 is a hydrocarbon group with 1 to 6 carbon atoms; R 2 is a hydrocarbon group with 1 to 12 carbon atoms or hydrogen; and R 3 is a hydrocarbon group with 1 to 12 carbon atoms) €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Formula 38€ƒ€ƒ€ƒ€ƒ€ƒRNSi(OR 1 ) 3 (where in Formula 38, R 1 is a hydrocarbon group with 1 to 6 carbon atoms; and RN is a cyclic1 amino group).
