(57) [Abstract] [PROBLEMS] To provide zinc oxide type fine particles having excellent transparency, ultraviolet ray shielding properties, infrared ray shielding properties such as heat rays, and electrical conductivity, and their use, and a low-production method with high productivity. . Kind Code: A1 A zinc oxide-based fine particle comprising a crystalline coprecipitate in which a group IIIB metal element or a group IVB metal element is added to zinc as a main metal element, and a mixture containing a zinc source, a monocarboxylic acid, and at least an alcohol. Is produced by heating in the presence of a compound containing a group IIIB metal element or a group IVB metal element. |
