The present invention relates to a heat sink, for a vehicular lamp, having improved heat dissipation performance and a method for producing the heat sink, the heat sink having improved heat dissipation performance by having carbon coating solution of superb heat conductivity and heat dissipation rate coated on the surface thereof, and being light-weight from not having a heat dissipating fan. The method for producing a sink sink, for a vehicular lamp, having improved heat-dissipation performance comprises the steps of: (S1) preparing a carbon coating solution; (S2) coating the surface of the surface-treated material with the carbon coating solution; (S3) hardening and cooling the carbon coating solution; and (S4) cutting and packaging the coated material after surface inspection, wherein the step (S1) for preparing the carbon coating solution comprises the steps of: (S10) producing nanocarbon mixed powder comprising, in wt%, 40-55% inorganic ceramic, 40-55% carbon black,1-4% carbon nanotubes, and 0.5-1% graphene; (S20) mixing and dispersing, in wt%, 30-50% the nanocarbon mixed powder, 30-50% distilled water, 1-10% dispersing agent, 0.1% organic acid, 5-20% polysiloxane, and 1-10% organic solvent, and then agitating and condensing to produce a nanocarbon mixed solution; and producing the coating solution by mixing, in wt%, 50-60% the nanocarbon mixed solution, 10-20% epoxy, 10-20% epoxy resin, 10-20% hardening agent, and 10-20% thinner.
