PROBLEM TO BE SOLVED: To provide a catalyst component for olefin polymerization capable of reducing content of a different shape powder contained in a polymerization powder, a catalyst and a manufacturing method for an olefinic polymer. SOLUTION: In the catalyst component for the olefin polymerization obtained by contacting a compound (a) represented by M<SP>1</SP>L<SP>1</SP><SB>m</SB>, a compound (b) represented by the formula, a compound (c) represented by R<SP>3</SP><SB>t-2</SB>TH<SB>2</SB>, and a particle (d), y and z satisfy the following formulae (1), (2) and (3) when a molar ratio of an amount used of the compound (a), (b), (c) used for the contact is made to (a):(b):(c)=1:y:z. The content of the particle (d) contained in the catalyst component for the olefin polymerization is 57-80 wt.%. ¾m-y-2z¾≤1 (1), z≥-2.5y+2.48 (2), y<0.5m (3). COPYRIGHT: (C)2009,JPO&INPIT |
