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.
