PROBLEM TO BE SOLVED: To provide a three-dimensional structure material suitable as a filter material capable of holding a large amount of a functional material especially for deodorizing, odor eliminating or air cleaning use, etc., and having low pressure loss, excellent processing capacity and flexibility. SOLUTION: This structure is achieved by the finding that a filter having unprecedented processing capacity and high flexibility can be produced by attaching rice chaff ash to the surface of a constitution fiber of a three-dimensional knit structure having interconnected holes and immobilizing a large amount of a functional material in the fine pores of the rice chaff ash.
