PROBLEM TO BE SOLVED: To provide an agricultural film having low material cost and working cost, capable of surely being fixed as a film for a tunnel without inhibiting growth of culture crops such as grape and pear, and further needing no fractional treatment when it is disposed as waste plastics. SOLUTION: Reinforcing belts 2 of thin width are placed on both the edges along the longitudinal direction of a long polyolefin film 1. Film bands 3 of >=20 mm and <=100 mm in width, and >=20 cm and <=50 cm in length are welded on the reinforcing belts 2 with a span of 50-70 cm by forming welded parts 4.
