PROBLEM TO BE SOLVED: To provide a conductive resin composition and a molded product thereof, excellent in conductivity of the molded product, having a low contact resistance, and penetration resistance, suitable for highly conductive material such as a separator for fuel cell, etc., even when the filling amount of conductive material is not sufficient. SOLUTION: The invention relates to the conductive resin composition (B) comprising at least a multi-component polymer-type resin binder (A) comprising a dispersed phase and a continuous phase, and having a number-average particle size of dispersed phase of 0.001-2μm, and a conductive material in the form of powder and/or fibers. In the multi-component polymer system having a micro phase separation form having sea-island structure of the dispersed phase and the continuous phase, the number average particle size of the island phase is smaller than the number average particle size of the conductive material and a high conductivity is realized by using the binder having 0.001-2μm of the number average particle size, and low contact resistance and low penetration resistance is realized by using an elastomer as a component of the binder.
