Abstract
A mixture of spherical graphite, carbon black and binder resin is fabricated. The mixture contains the spherical graphite of not less than 50 parts by weight and not more than 70 parts by weight, the carbon black of not less than 1 part by weight and not more than 15 parts by weight and the binder resin of not less than 15 parts by weight and not more than 40 parts by weight, to 100 parts by weight of the mixture. The binder resin includes thermosetting resin and elastomer, and an average particle diameter of the spherical graphite is not less than 1 μm and not more than 30 μm. The conductive composition including the mixture can be used for a collector such as a fuel cell.
