Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of an olefin polymer capable of providing the olefin polymer at high yield by suppressing side reactions.SOLUTION: A manufacturing method of an olefin polymer by polymerizing an olefin monomer in presence of concentrated sulfuric acid with controlling a temperature at 0 to 60°C is used. Concentration of sulfuric acid contained in the concentrated sulfuric acid is preferably 96 wt.% or more and mixed weight ratio of the olefin monomer and the concentrated sulfuric acid (olefin monomer:concentrated sulfuric acid) is preferably 10:1 to 1:5.SELECTED DRAWING: None 【課題】副反応を抑制しオレフィン重合体を高収率で得ることができるオレフィン重合体の製造方法を提供することを目的とする。【解決手段】濃硫酸存在下でオレフィン単量体を０〜６０℃に温調しながら重合させるオレフィン重合体の製造方法を用いる。濃硫酸に含まれる硫酸の濃度が９６％重量以上であることが好ましく、オレフィン単量体と濃硫酸との混合重量比（オレフィン単量体：濃硫酸）が、１０：１〜１：５であることが好ましい。【選択図】なし
