A process for producing an olefin polymer through olefin polymerization in the presence of a metallocene transition metal catalyst, while preventing polymer deposition on the reactor wall and preventing the generation of a sheet-form polymer, massive polymer, etc. to stably conduct the polymerization operation over long. The process is characterized by polymerizing an olefin in the presence of [A] a metallocene transition metal catalyst and [B] an organoaluminum compound represented by the general formula R1n Al(OR2)3-n (wherein R1 represents C¿1-20? alkyl, aryl, hydrogen, or halogeno; R?2¿ represents C¿1-20? alkyl or aryl; and n is a number satisfying 0≤n∫3) under such conditions that the temperature of the polymerizer wall, tw (°C), and the polymerization temperature, tr (°C), satisfy the following relationship 1: 0.5 < tr-tw < 10. |
