PROBLEM TO BE SOLVED: To provide an artificial pumice containing a hydrolytic collagen and made of a hard synthetic resin foamed body. SOLUTION: The artificial pumice is completed by feeding a prescribed amount of a powdery hydrolytic collagen 11 and a gelled liquid hyaluronic acid 12 to a chemical before being foamed and admixing them preliminarily so that they are evenly dispersed in the chemical, then foaming them through a usual foaming process. Furthermore, a copper powder 13 may be added into the chemical preliminarily. Since the anti-bacterial property is enhanced thereby, it is more hygienic. COPYRIGHT: (C)2006,JPO&NCIPI
