PROBLEM TO BE SOLVED: To provide an agricultural polyethylene terephthalate film durable against outdoor spreading under tension for a long period with excellent weatherability and defogging persistence. SOLUTION: A defogging film is formed on one surface of a biaxially oriented polyethylene terephthalate film and a thermoplastic resin film contains specific acrylic resin containing ultraviolet absorbent and having a thickness of 1 to 10μm and saturated polyester resin as main components is formed on the other surface. Thus, since the terephthalate film has excellent transparency and weatherability and has the defogging film and the thermoplastic resin film containing the absorbent, the excellent defogging properties are continued for a long period, and hence its utilizing value as an agricultural film is large.
