PROBLEM TO BE SOLVED: To provide an agricultural house that inhibits condensation inside a lining film and also has a high light transmittance.SOLUTION: An agricultural house 10 comprises an outer coating film 1 that forms a space separated from the outside, a lining film 2 provided inside the outer coating film so as to have a gap with the outer coating film, and ventilation means 4 for ventilation between at least part of the air in the gap and the outside air. At least part of the lining film is composed of a cellulose film that comprises cellulose acylate resin and has a moisture permeability of 600 g/m/24 h or more.SELECTED DRAWING: Figure 4【課題】内張りフィルムの内側の結露を抑制し、かつ、光線透過率の高い農業ハウスを提供する。【解決手段】農業ハウス10は、外部から仕切られた空間を形成する外張りフィルム1と、外張りフィルムの内側に、外張りフィルムと隙間を有するように設けられる内張りフィルム2と、隙間に存在する空気の少なくとも一部と外部の空気とを換気する換気手段4と、を有し、内張りフィルムの少なくとも一部が、セルロースアシレート樹脂を含有し、透湿度が600g/m2/24h以上のセルロースフィルムで構成されている、。【選択図】図4
