A catalyst for use in the polymerization of at least one olefin comprising [A] a catalyst component comprising a compound of a transition metal of Group IVB of the Periodic Table having a ligand containing a -SO3R group wherein R is an alkyl group, an alkyl group substituted with a halogen atom, an aryl group, or an aryl group substituted with a halogen atom or an alkyl group, and a ligand having a cyclopentadienyl skeleton, and [B] an organoaluminum oxy-compound. This provides an olefin polymer having excellent particle properties at high polymerization activities, and enables the production of a copolymer having a narrow composition distribution. The transition metal compound preferably is a novel compound of the formula (Cp is a group having a cyclopentadienyl skeleton, R is an optionally substituted alkyl or aryl group, and X is SO3R, a halogen atom, R, OR, NRn, S(O)qR, SiR3 or P(O)qR3, wherein n = 1, 2 or 3; q = 0, 1 or 2).
