    a step of polymerizing olefins including ethylene, in the presence of an olefin polymerization catalyst comprising:
    [A] a solid titanium catalyst component including magnesium, halogen, titanium and a polyether compound represented by the following general formula (2), and

    [B] an organometallic compound catalyst component including a metal element selected from group I, group II and group XIII of the periodic table; and
    (c) a step of subjecting the polymer obtained in the above step to a temperature of not less than 100°C and not more than a melting point of the polymer for 15 minutes to 24 hours;

    wherein m is an integer of 1≤m≤10; R 11 to R 36 represent each independently a hydrogen atom or a substituent having at least one element selected from carbon, hydrogen, oxygen, fluorine, chlorine, bromine, iodine, nitrogen, sulfur, phosphorus, boron and silicon; when m represents 2 or more, a plurality of R 11 s and R 12 s may each be the same or different; and any of R 11 to R 36 may together form a ring other than a benzene ring.
