This invention provides an olefin polymer production method by which olefin polymers can be obtained at high polymerization activity under the conditions of reduced hydrogen concentration and provides silyl-terminated olefin polymers obtained by this production method. The olefin polymer production method is characterized in that an olefin is polymerized under the presence of a catalyst comprising a transition metal compound (A) of Groups 3 to 10 of the periodic table, at least one compound (B) selected from among organoaluminum oxycompounds (B-1), compounds (B-2) that react with the abovementioned compound (A) to form an ion pair, and organoaluminum compounds (B-3), and under the coexistence of an organosilicon compound (C) or dialkylzinc compound (D) and hydrogen (E). This invention also provides an olefin polymer production method by which olefin polymers can be obtained at high polymerization activity and provides silyl-terminated olefin polymers obtained by this production method. This olefin polymer production method is characterized in that an olefin is polymerized under the presence of a catalyst comprising a transition metal compound (A-i) of Groups 3 to 10 of the periodic table, at least one compound (B) selected from among organoaluminum oxycompounds (B-1), compounds (B-2) that react with the abovementioned compound (A-i) to form an ion pair, and organoaluminum compounds (B-3), under the coexistence of an organosilicon compound (C) or dialkylzinc compound (D), and under the non-presence of hydrogen (E).
