Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a cyclodextrin-containing composite material to be provided in optional size and shape. SOLUTION: The method for producing the cyclodextrin-containing composite material comprises: a step P1 of adding cyclodextrin 1 under an alkaline condition; a step P2 of adding amorphous silicic acid 2 to the system; and a step P3 of further adding an epoxy compound 3 such as epichlorohydrin, ethylene glycol diglycidyl ether and butanediol diglycidyl ether to the resulting system. A material 4 being a medium, which is selected from a wood chip, a cellulose compound and plastics and on which a cyclodextrin polymer will be deposited, is added before the step P3, simultaneously with the epoxy compound 3 or during the step P3. As a result, an epoxy compound-cross-linked cyclodextrin polymer-containing composite material (a multiple component material) 10 can be obtained. COPYRIGHT: (C)2010,JPO&INPIT
