PROBLEM TO BE SOLVED: To provide a surface-treated inorganic powder that hardly suffers from aggregation and is highly stable. SOLUTION: The surface-treated inorganic powder comprises an inorganic powder surface-treated with a surface-treating agent that is an organic compound having a polar part and a non-polar part and is liquid at ordinary temperature. Use of such a surface-treating agent permits protection of functional groups present on the surface of the inorganic powder and therefore effective suppression of aggregation of the inorganic powder. When a substance bearing at least one functional group selected from the group consisting of an amino group, epoxy group, acryl group, methacryl group, hydroxy group, carboxy group, thiol group and vinyl group in the polar part and/or a substance having a hydrocarbon group having a molecular weight of 50-1,000 in the non-polar part is used, the surface-treated inorganic powder exhibits higher preservability. Concrete examples of preferable surface treating agents include an epoxy reactive diluent and an acrylic reactive diluent. COPYRIGHT: (C)2008,JPO&INPIT
