    Abstract: A catalyst for polymerization of an olefin, is provided which contains a solid catalyst component (A) obtained by supporting a transition metal compound having formula (1): ##STR1## onto a solid inorganic compound, and then washing the solid inorganic compound with a nonaqueous solvent capable of dissolving the transition metal compound, where M is a transition metal of Group 4b; X.sup.1 and X.sup.2 are, independently, a halogen, hydrogen, an alkylalkoxy group, a saturated or unsaturated alkyl group; R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are, independently, hydrogen or a saturated or unsaturated C.sub.1-100 alkyl group; m is an integer of 1 to 6; and p and q are, independently, an integer of 0 to 4, and a catalyst component (B) containing an organic aluminum compound having formula (2): ##STR2## where 1, is an integer of 2 to 100, R.sup.5 is a C.sub.1-6 alkyl group, and/or an organic aluminum compound having formula (3) ##STR3## where 1' is an integer of 2 to 100, and R.sup.5 is a C.sub.1-6 alkyl group. A process for producing an olefin polymer is also provided in which this catalyst is employed. The catalyst is prepared with low amounts of organic aluminoxane, yet has high activity.
