Research Abstract	Fabrication of a microcapsule containing microspheres which can adsorb metal ions via ion-exchange was investigated. Microencapsulation of the ion-exchange microspheres were performed by using a cage-like microcapsule which has many holes in the shell. The microspheres were formed in the microcapsule : a microcapsule containing many microspheres was successfully prepared. On the other hand, the functionalization of the microspheres which can be formed in the microcapsules was performed by grafting polymer chains having a reactive group with a metal ion. The metal adsorption amount of the prepared microsphere was almost same to the other melamine-based ion-exchange resins.
