Abstract
An electroconductive particle having a core particle and a tin oxide-containing coating layer on the core particle. The tin oxide of the coating layer has a crystallite size of 70 to 200 Å. The electroconductive particle preferably has a ratio of Rto Rof 1 to 250, wherein Rand Rare respective surface resistivities of electroconductive films formed of a coating composition containing the electroconductive particle and prepared by 1-hour dispersing and 3-hour dispersing, respectively. The coating layer preferably comprises dopant element-free, electroconductive tin oxide.
