OG exemplary drawing
 
1. An insulating heat-radiating coating composition, comprising:
a coating layer-forming component comprising a main resin;
an insulating heat-radiating filler comprised in an amount of 35 to 60 parts by weight based on 100 parts by weight of the main resin, and
a dispersant comprised in an amount 0.5 to 20 parts by weight based on 100 parts by weight of the insulating heat-radiating filler,
wherein the insulating heat-radiating filler has an average particle diameter of 10 nm to 15 μm, and in the insulating heat-radiating filler, a ratio of D50 to D97 is 1:4.5 or less, and
wherein the main resin comprises a compound represented by Formula 1:
