The present invention relates to a molded article which is shaped of a polymer composition comprising 100 parts by weight of an olefin-based polymer, and 0.01 to 100 parts by weight of a C10-90 saturated chain hydrocarbon and/or liquid paraffin and 0.01 to 200 parts by weight of a releasable active compound per 100 parts by weight of said olefin-based polymer, and which is drawn at a draw ratio of 2 or more.
