PROBLEM TO BE SOLVED: To provide a filter member capable of suppressing falling of ion exchange resin particles.SOLUTION: A sheet-like filter member for removing ion includes: ion exchange resin particles 1 expanding by at least either of swelling and adsorption of ion, and contracting by at least either of drying and separation of ion; and a binder 2 whose shape is changed reversibly following expansion and contraction of the ion exchange resin particles 1. 【課題】イオン交換樹脂粒子の脱落を抑制することが可能なフィルター部材の提供。【解決手段】イオンを除去するためのシート状のフィルター部材は、膨潤およびイオンの吸着の内の少なくとも一方によって膨張し、乾燥およびイオンの分離の内の少なくとも一方によって収縮するイオン交換樹脂粒子１と、形状が、イオン交換樹脂粒子１の膨張および収縮にともなって可逆的に変化するバインダー２と、を備える。【選択図】図２
