PROBLEM TO BE SOLVED: To provide a high molecular weightα-olefin polymer having specific properties prepared by using a 12-30Cα-olefin as a raw material, and to provide a method for efficiently producing the same. SOLUTION: Theα-olefin polymer is a polymer of one or more 8-30Cα-olefins and satisfies the following (1) and (2): (1) the weight-average molecular weight (Mw) in terms of polystyrene measured by the gel permeation chromatography (GPC) is 1,000,000 or more, and (2) the molecular weight distribution (Mw/Mn) determined from the weight-average molecular weight (Mw) and the number average molecular weight (Mn) in terms of polystyrene measured by the gel permeation chromatography (GPC) is 3-20. The method for producing anα-olefin polymer comprises polymerizing a 12-30Cα-olefin at 40°C or below in the presence of a catalyst comprising a solid catalyst component containing a magnesium compound and a titanium compound.
