PROBLEM TO BE SOLVED: To obtain a film excellent in adhesion to an antifogging coating film and a thermoplastic resin and further not only dustproof properties, strength and transparency but also antifogging persistence, weather resistance, etc. SOLUTION: This agricultural film has [I] a thermoplastic resin film layer formed of (C) a resin composed of (A) an ethylene-α-olefin copolymer having 0.880-0.940 g/cm<3> density and 0.01-10 g/10 min melt flow rate(MFR) or (C) the resin composed of a mixture of the component A with (B) a high-pressure- processed low-density polyethylene in an amount of <=40 wt.% and [II] a coating layer formed on at least one surface of the film layer [I] and comprising (D) a surface coating type antifogging agent composition containing a colloidal hydrophilic inorganic compound and a hydrophilic compound. The component A of the resin C or the mixture of the components A with B has 1.5-3.5 Mw/Mn and the fraction of the content soluble in n-decane at 23 deg.C and the density satisfy a specific relationship. When the average value of number of branches on the high-molecular weight side is B1 measured by the gel permeation chromatography-infrared spectrophotometry(GPC-IR) and that on the low- molecular weight side is B2 , B1 >=B2 .
