Capillary phenomenon is a physical phenomenon that fine meshes and structure with gaps absorb liquids, and three of them are related to (1) surface tension of liquid (2) wettability of solid and liquid (3) diameter of capillary. The surface tension of the liquid depends on the temperature of the liquid although this phenomenon is common in nature, there are not much design and fabrication of metamaterials that control liquids by using capillary phenomena. In this study, we design and fabricate a metamaterial structure that computationally generates capillary phenomena. We verify the features of its shape, change in water level, moisture content, and propose an optimal structure. We evaluated the change of the water level in the structure and the change of water content by changing the size of the gap of the structure and the temperature of the liquid. The structure of this study can propose a new vase for arrange flowers by absorbing water from the lower of the structure. Also, the structure can be aimed at decreasing the temperature inside the building by attaching it to the surface of the building. 　本研究では，毛細管現象により含水率を自在に変えることができる新しいメタマテリアルのデザイン手法を提案します． 　毛細管現象は，細かい網目や隙間を持つ物体が液体を吸収する現象で，(1)液体の表面張力 (2)固体と液体の濡れやすさ(3)毛細管の直径の3つが関係しています．液体の表面張力は液体の温度に依存します．この現象は自然界には多く見られますが，毛細管現象を用いて液体物をコントロールするようなメタマテリアルの設計とファブリケーションはあまり行われていません． 　そこで本研究では，コンピューターを用いて毛細管現象を発生させるメタマテリアル構造を設計，ファブリケーションし，その形状の特徴，水位の変化，含水率について検証し，最適な構造の提案をします．その上で，構造の隙間の大きさと液体の温度を変化させ，構造内の水位の変化と含水量の変化を説明します． 　本研究の構造は下から水を吸い上げ，植物を生けることができる新しい花瓶を提案出来ます．また，ビルの表面にその構造を取り付けることでビル内の温度の低下を目指すことができます．
