PROBLEM TO BE SOLVED: To provide a method for producing a bead-shaped cyclodextrin polymer capable of simplifying the production process and eliminating a process with a large environmental load. SOLUTION: Cyclodextrin 1 is added under alkaline conditions (P1), amorphous silicic acid 2 is added thereto (P2), and epichlorohydrin 3 is further added thereto (P3). To obtain the beaded cyclodextrin polymer 10. Instead of the amorphous silicic acid 2, a silicate such as sodium silicate or potassium silicate, or an aqueous solution thereof may be added.
