The present invention aims at providing a solid catalyst component for olefin polymerization, the solid catalyst composed being capable of showing a sufficiently high polymerization activity and providing a polymer having a low content of a low molecular weight component or an amorphous component; a process for producing the solid catalyst component; and a process for producing a solid catalyst for olefin polymerization, and a process for producing an olefin polymer. This object can be achieved by a process for producing a solid catalyst component (A), the process including: step (1) of producing a precursor of the solid catalyst component by adding an organomagnesium compound (c) to a titanium compound (b) represented by Formula (I) in the presence of a silicon compound containing a Si—O bond (a); and step (2) of producing the solid catalyst component (A) by bringing the precursor of the solid catalyst component, a halogenated metal compound represented by Formula (II) and an internal electron donor represented by Formula (III) into contact with each other.
