PROBLEM TO BE SOLVED: To obtain negative ion generating powder that generates negative ions even without using a natural ore and reduces the cost of a product for generating negative ions and a negative ion generating molding. SOLUTION: The negative ion generating powder is obtained by using an inorganic composition comprising potassium carbonate, potassium nitrate and calcium carbonate as essential components. Namely, the negative ion generating powder is obtained by heating and melting the inorganic composition, quenching and powdering the molten composition. COPYRIGHT: (C)2005,JPO&NCIPI
