PURPOSE: To obtain a catalyst, comprising a specific transition metal, having excellent polymerization activity for an olefin and capable of producing a polyolefin, having a high molecular weight and a high melting point and excellent in stereoregularity. CONSTITUTION: This transition metallic compound is expressed by the formula (M is a group IVa, Va or VIa transition metal of the Periodic Table; R1 is H, a halogen, a 1-20C halogenated hydrocarbon, a silicon-containing group, etc.; R2 is a 1-20C hydrocarbon which may be substituted with a halogen, etc.; Hal is fluorine or chlorine; X and X are each H, a halogen, a 1-20C hydrocarbon, etc.; Y is a 1-20C bivalent hydrocarbon, SO, etc.). Furthermore, the catalyst for polymerizing an olefin comprises the transition metallic compound and is prepared by supporting the transition metallic compound, an organoaluminumoxy compound and a compound, reactive with the metallic compound and forming an ion paxr on a particulate carrier. The method for polymerizing the olefin comprises a reaction in the presence of the catalyst.
