The present invention addresses the problem of providing: a conductive pigment paste which exhibits excellent pigment dispersibility and excellent storage stability even in cases where the pigment concentration is high; a coating material; and a coating film which exhibits excellent finish properties and the like. The present invention provides, as a means for solving the problem, a conductive pigment paste which contains (A) a pigment dispersion resin, (B) a conductive pigment, (C) a solvent and (D) a fluororesin, wherein: the pigment dispersion resin (A) has at least one a polar functional group that is selected from the group consisting of an amide group, an imide group, a hydroxyl group, a carboxyl group, a sulfonic acid group, a phosphoric acid group, a silanol group, an amino group and a cyano group; the polar functional group concentration in the pigment dispersion resin (A) is from 10 mmol/g to 23 mmol/g; the conductive pigment (B) has an average primary particle diameter of 10 nm to 80 nm and a BET specific surface area of 250 m2/g or less; the solubility parameter δA of the pigment dispersion resin (A) and the solubility parameter δC of the solvent (C) satisfy the relational expression |δA - δC| < 2.0; and the viscosity at a shear rate of 0.1 s-1 is less than 5,000 mPa·s.
