PROBLEM TO BE SOLVED: To provide a method of improving heat radiation efficiency of electronic equipment whose heat generating source is covered with a resin material by improving heat transmittance of the resin (making transparent), and to provide a wavelength selective heat radiating material and a method of manufacturing the same. SOLUTION: In the electronic equipment which has its heat generating source covered with the resin member having a specified infrared-ray transmission wavelength range, the wavelength selective heat radiating material having a heat radiation surface where many microcavities forming a periodic surface fine unevenness pattern are arrayed in two dimensions is disposed between the heat generating source and resin member to cover the heat generating source, heat energy from the heat generating source is applied to the wavelength selective heat radiating material through heat conduction or heat radiation, and heat radiation light corresponding to the infrared-ray transmission wavelength range of the resin material is selectively radiated from the heat radiation surface of the wavelength selective heat radiating material to the resin member to improve the heat radiation efficiency of the electronic equipment.
