The radiant heat circuit board includes a metal plate comprising an integrated metal projection to which the plurality of heat generating devices are attached, an insulation member exposing the integrated metal projection, the insulation member comprising a plurality of insulation layers disposed on the metal plate, and first and second electrode pads disposed on the insulation member, the first and second electrode pads disposed being electrically separated from each other. The first and second electrode pads receives a voltage from circuit wires disposed on the insulation layers different from each other of the insulation member. Thus, a radiant projection may be disposed between the heat generating devices to improve heat radiation.

Disclosed are a radiant heat circuit board and a method for manufacturing the same. The radiant heat circuit board, which is used to mount a heat emitting device thereon, includes a metallic plate including a metallic protrusion having a solder to which the heat emitting device is attached, a bonding layer on the metallic protrusion, an insulating layer on the metallic plate to expose the metallic protrusion, and a circuit pattern on the insulating layer. Heat emitted from the heat emitting device is directly transferred to the metallic plate by providing the metallic plate including a heat radiation protrusion under the mounting pad, so that heat radiation efficiency is increased. The surface of the heat radiation protrusion is plated with an alloy including copper, thereby improving the adhesive property with respect to the solder, so that the failure rate is reduced.

An epoxy resin composition having an epoxy resin, a curing agent, and inorganic filler as main components is provided. The epoxy resin includes an epoxy resin of Chemical Formula. Accordingly, the thermal conductivity of the epoxy resin composition can be increased because the epoxy resin has a mesogen structure that facilitates crystallizability. In addition, a high radiant heat board can be provided by using the above-mentioned epoxy resin as an insulating material for a printed circuit board.
