PROBLEM TO BE SOLVED: To provide a fiber structure having excellent cesium ion adsorption ability in which a cesium ion adsorbent is fixed firmly with very little falling; and to provide a production method thereof.SOLUTION: In a fiber structure for cesium ion adsorption, a cesium ion adsorbent is fixed by a low melting-point component of a fiber or by a binder, which is a fiber structure containing two or more kinds of fibers having a melting point difference of 30°C or more and/or fibers which are adjacent to a polymer having a melting point difference of 30°C or more, or which form a core-sheath structure together therewith.SELECTED DRAWING: None |
