Abstract
The invention provides a specific metallocene compound and an olefin polymerization catalyst for use for a catalyst for producing an olefin polymer having a sufficiently high molecular weight while maintaining excellent copolymerizability at a polymerization temperature and under polymerization conditions industrially advantageous in polymerization of an olefin such as ethylene or the like, and provides a method for producing an olefin polymer using the catalyst.
