PROBLEM TO BE SOLVED: To provide a coating agent for improving the conductance of electrical connections such as plugs, terminals, jacks, connectors, switches and other terminals of electrical or electronic parts.;SOLUTION: The conductance-improving agent is a mixture of graphite carbon and squalane characterized in that the graphite carbon is 20 wt.% or less and amorphous carbon is 5 wt.% or less and that the graphite carbon is composed of particles of a μm size and particles of an nm size, wherein the particles of a μm size are 10 to 20 wt.% and the particles of a nm size are 90 to 80 wt.% of the whole graphite carbon. The coater 1 of the conductance-improving agent is characterized by being equipped with a pen type cylindrical body for holding the conductance-improving agent and a core for discharging the conductance-improving agent in the pen type cylindrical body.;COPYRIGHT: (C)2010,JPO&INPIT
