摘要

PROBLEM TO BE SOLVED: To provide crystalline conductive particulates that can be used in the formation of a base material with a transparent conductive film, having a low surface resistance of about 107 /(square) or lower, of superior a antistatic property and an electromagnetic wave shielding property, having low luminous reflectance and excelling in an antireflective property, and to provide a manufacturing method of the particulate; and the like. SOLUTION: The crystalline conductive particulate has void ratio in the range of 0.10 to 0.60 ml/g. The manufacturing method of the crystalline conductive particulate comprises a step of adding a doping agent, if necessary, to a solution of metal salt in water and adding alkali to the mixture for hydrolysis to prepare hydrous oxide particles or doped hydrous oxide particles of the metal; a step of filtering and washing the hydrous oxide particles or doped hydrous oxide particles; a step of dispersing the washed hydrous oxide particles or doped hydrous oxide particles in water and maturing the solution at 50 to 350 deg.C; a step of filtering out and drying the metal hydroxide or doped hydrous oxide particles in the matured dispersion solution; and a step of baking the dried hydrous oxide particles or doped hydrous oxide particles at 200 to 800 deg.C.
