Abstract: Solid fine particles which bear magnesium, aluminum, and C1-20 alkoxy, are insoluble in hydrocarbon solvents, and have a mean particle diameter of 3 to 80μm; and catalysts for olefin polymerization containing the solid fine particles and Group 3-11 transition metal compounds. The catalysts exhibit extremely high olefin polymerization activity even when they are not combined with an expensive organoaluminum oxy compound or an organoboron compound, and can keep high activity over long-time polymerization and give efficiently olefin polymers excellent in powder characteristics. The Group 3-11 transition metal compounds include those having ligands which each contain at least two elements selected from among boron, nitrogen, oxygen, phosphorus, and sulfur.
