PROBLEM TO BE SOLVED: To reduce manufacturing cost and secure deodorization effects.SOLUTION: On a porous base material 3, multiple depressed cavities 7 are formed that open on the front face side. On the front face of the porous base material 3, a coating film 5 is applied and formed that has a water dispersion resin as a main component and contains a filler. In the coating film 5, a penetration cavity 9 smaller than the depressed cavity 7 of the porous base material 3 and penetrating the coating film 5 is formed to communicate with the depressed cavity 7.COPYRIGHT: (C)2013,JPO&INPIT【課題】製造コストを削減するとともに、消臭効果を確実に得る。【解決手段】多孔質基材3に表面側に開口する多数の凹陥空隙7を形成するとともに、多孔質基材3の表面に、水分散樹脂を主成分とし、かつ充填材を含有する塗膜5を塗布形成する。塗膜5には、多孔質基材3の凹陥空隙7よりも小さく塗膜5を貫通する貫通空隙9が凹陥空隙7に連通するように形成される。【選択図】図1
