  A solid catalyst for olefin polymerization and a process for producing an olefin polymer are provided. The polymer has a small content of a component which is dissolved out into a low temperature organic solvent, such as a low-molecular weight component and an amorphous component. The solid catalyst is obtained by bringing a solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an aliphatic carboxylate; an organoaluminum compound; and a compound represented by formula (I) into contact with each other: wherein R 1 is a hydrocarbyl group having 1 to 10 carbon atoms, R 2 is a hydrogen atom, a halogen atom or a hydrocarbyl group having 1 to 16 carbon atoms, and the R 1 the R 2 groups are independently the same or different, and the respective R 1 groups and R 2 groups may be joined with each other to form a ring.
