According to the present invention there is provided a catalyst component capable of affording an olefin polymer of a high molecular weight and a relatively wide molecular weight distribution in a small amount of a modified aluminum compound used and in high yield. The catalyst component is prepared by contacting the following constituents (1), (2) and (3) with one another: (1) a compound represented by the general formula MeRp(OR')qX4-p-q where X is a halogen atom, Me is Zr, Ti, or Hf, p and q are in the ranges of 0 ? p ? 4 and 0 ? q ? 4, provided 0 ? p+q ? 4, (2) a compound represented by the general formula MeHmR3-m' Me'¢MeHpRq(OR)4-p-q!z, or <IMG> where Me is a Group 13 element, Me' is a Group 1, 2 or 12 element, Z is the valence of Me', and m, n, p and q are in the ranges 0 ? m ? 3, 0 ? n ? 4, 1 ? p ? 4 and 0 ? q ? 3, provided 1?p+q?4, and (3) an organocyclic compound having two or more conjugated double bonds.
