CONDUCTIVE PARTICLE AND CONDUCTIVE COMPOSITION INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide conductive particles from which an electric conductor is produced, the electric conductor having an electric resistance being hard to depend on an applied voltage.SOLUTION: The conductive particle according to the present invention has a core containing inorganic substance and a coating layer provided on the surface of the core and containing electric conductive tin oxide. When D1 is a crystallite diameter of the tin oxide calculated using Halder-Wagner method by X-ray diffraction measurement and D2 is a primary particle size of the tin oxide measured by transmission electron microscope observation, a value of D1/D2 is 0.1-1.0. It is preferred that the value of D1 is 4-20 nm, and the value of D2 is 4-50 nm.SELECTED DRAWING: None
