PROBLEM TO BE SOLVED: To provide insulation-coated conductive fine-grains which can be applied to finer wiring, which have no problems related to electric capacity at the time of connection to achieve stable connection without causing a leak phenomenon, and which can achieve electric continuity without using a high temperature or a high pressure. SOLUTION: In insulation-coated conductive fine-grains comprising conductive fine-grains of an average grain diameter of 0.5-1000μm, an aspect ratio of less than 2, and a CV value of 30% or less, and a coating layer comprising an insulating resin of a thickness of 1/30000-1/3 of the average grain diameter of the conductive fine-grains formed on the surface of them, the insulating resin does not have autohesion performance or fluidity at a room temperature, its fluidity is increased at it is heated, and its viscosity becomes 10.0000 Pa.s or less at 140 deg.C.
