Abstract: A printed board is able to cool an electronic component with high efficiency without requiring a heatsink for cooling the electronic component while preventing upsizing of the electronic device. A method for manufacturing such a printed board with high efficiency is also disclosed.

Therefore, the heat generated by the electronic component can be reliably radiated by heat conduction to the carbon layer and heat diffusion through the carbon layer, thereby cooling the electric component with high efficiency.
