[Problems] To eliminate waste of agricultural water that is evaporated in farmland, to eliminate the need for a huge investment when obtaining drinking water from seawater, to eliminate restrictions on the installation location, and to assemble without separate manufacturing for each part. To provide a condenser for using condensed water as agricultural water or drinking water without labor. A condensing section 5 of a condenser, a steam supply/generation source and a condenser body are connected, a pipe 1 for introducing steam into the condensing section of the condenser, and condensed water is used as agricultural water and drinking water. It consists of an extraction tube 3, which has a part 4 for collecting the condensed water introduced into the condenser and a part 2 for collecting and removing the condensed water. [Selection drawing] Fig. 1【課題】農地で蒸散させている農業用水の無駄をなくし、海水から飲料水をえる場合には巨額の投資を不要とし、しかも設置場所に制約をなくし、部分ごとに分離製作せずに組み立ての手間を不要とした、凝縮水を農業用水や飲料水として利用する凝縮器を提供する。【解決手段】凝縮器の凝縮部5と、蒸気の供給、発生源と凝縮器本体を接続し、凝縮器の凝縮部へ蒸気を導入する管1と、凝縮した水を農業用水、飲料水として抜き出すチューブ3で構成し、管には凝縮器内部に導入され凝縮した水を集合させる部分4並びに凝縮水を回収し取り出す部分2を備える。【選択図】図1
