Summary:PROBLEM TO BE SOLVED: To provide a membrane which is suitable for use with a fuel cell and is further inexpensive with durability and dimensional stability improved.SOLUTION: A membrane 1 includes a central region 2 including (a) ion conductivity polymeric materials, and (b) a boundary region 3 forming a frame around the central region 2, and made of one or more non-ionic conducting materials to form at least one layer of the one or more non-ionic conducting materials. The non-ionic conducting materials of the boundary region 3 overlap the ion conductivity polymeric materials of the central region 2 in an overlapping region 4 of 0 to 10 mm.SELECTED DRAWING: Figure 1 【課題】燃料電池での使用に適した膜であって、耐久性および寸法安定性が増している、より低コストの膜の提供。【解決手段】（ａ）イオン伝導性高分子材料を含む中央領域２と、（ｂ）中央領域２の周りにフレームを形成し、１つ以上の非イオン伝導性材料から成る境界領域３であって、１つ以上の非イオン伝導性材料の少なくとも１つが層を形成する、境界領域３と、を備え、境界領域３の非イオン伝導性材料は、０〜１０ｍｍの重なり領域４にて中央領域２のイオン伝導性高分子材料と重なり合っている、膜１。【選択図】図１
