PROBLEM TO BE SOLVED: To provide an air cell hard hardly causing a bottom touch or the like while making use of a characteristic of a conventional air cell without complicating control or a structure of the air cell, and to provide an air mat including the same.SOLUTION: This air cell 10 is made of a long bag-like film. A plurality of air cells 10 are provided side by side to constitute the air mat. The air cell has a vertical multilayer structure 11, 12, 13, and is formed such that air flows between respective layers. When air is supplied from an air supply port 16, the respective layers have the same air pressure. A lower layer part 13 of the air cell is formed in a double structure having a shape that films 131, 132 overlap inside and out, and the lower layer part surface is also provided with another air supply port 17.COPYRIGHT: (C)2012,JPO&INPIT【課題】エアセルの構造や制御が複雑にならず、かつ従来からのエアセルの特徴を生かしつつ、底着きなどを起こしにくいエアセルとこのエアセルを備えたエアマットの提供すること。【解決手段】複数本並設することによりエアマットを構成する細長い袋状のフィルムからなるエアセル10であって、かつ該エアセルが上下方向に多層構造11,12,13で、各層間はエアが流動するように形成され、給気口16からエアが供給されると各層とも同じエア圧となるエアセルにおいて、前記エアセルの下層部13をフィルム131,132が内外重なり合う形状の二重構造に形成して、その下層部表面にも他の給気口17を設けた。【選択図】図1
