PROBLEM TO BE SOLVED: To provide an agricultural polyolefinic multilayered film reduced in the lowering of transparency and ultraviolet transmission suppressing effect caused by the bleeding of an ultraviolet absorber, suppressing the generation of the damage of crops by blight and noxious insects over a long period of time, generating no discoloration even if the addition amount of an ultraviolet absorber is increased, also good in anti-fogging properties and suitable as a cover film of a horticultural facilities. SOLUTION: In the agricultural polyolefinic multilayered film having a multilayered structure having at least an inner layer, an intermediate layer and an outer layer, the inner layer is constituted of a composition of a specific ethylene/vinyl acetate copolymer and the intermediate layer is constituted of a polyolefinic resin containing 0.005-3.5 weight % of an ultraviolet absorber and 0.005-1.0 weight % of a hindered phenolic oxidation inhibitor with a melting point of 100-200 deg.C and a mean molecular weight of 1,000 or more and the outer layer is constituted of a composition of low density polyethylene or an ethylene/α-olefin copolymer with specific density and the mean transmissivity of ultraviolet rays with a wavelength of 280-400 nm of the whole multilayered film is 10% or less and the total light transmissivity thereof is 70% or more.
