PROBLEM TO BE SOLVED: To provide a fiber structure having excellent cesium adsorption ability, to which a cesium adsorbable metal complex is firmly fixed at high concentration so as to rarely fall off without using an adhesive binder, and a manufacturing method of the fiber structure.SOLUTION: A cesium adsorbing fiber structure to which a cationic polymer compound containing tertiary or quaternary ammonium groups and a cesium ion adsorbable metal complex are fixed satisfies specific cesium ion adsorption ability (a), specific cesium ion adsorption amount (b), and specific discoloration and liquid contamination ability of the fiber structure (c). |
