PROBLEM TO BE SOLVED: To provide a conductive composition allowing reduction in thickness and improvement of conductivity and handleability, a conductive composition sheet, a conductive substrate, a collector sheet, a wiring circuit board, a fuel battery, and a manufacturing method of the conductive composition.SOLUTION: A mixture of spherical graphite, carbon black and a binding resin is manufactured. The mixture contains 50 pts.wt. or more and 70 pts.wt. or less of the spherical graphite, 1 pt.wt. or more and 15 pts.wt. or less of the carbon black, and 15 pts.wt. or more and 40 pts.wt. or less of the binding resin, when the mixture is 100 pts.wt. The binding resin comprises a thermosetting resin and an elastomer and the spherical graphite has an average particle diameter of 1 μm or more and 30 μm or less. A conductive composition comprising the mixture can be used for a collector 1 of a fuel battery and the like. |
