A gas jetting device capable of effectively dissipating heat generated from an exothermic body while controlling the generation of noise as much as possible; an electric device equipped with the gas jetting device; and a gas jetting method. The gas jetting device (1) has a vibrating body (25). When gas is jetted from nozzles (23, 24) with sound waves produced therefrom, the gas jetting device causes the gas to be jetted as a pulsating flow by the vibrations of the vibrating body (25) in such a manner that the sound waves cancel each other. Further, a controller (20) controls the frequency of the vibrating body (25) to an optimum value to increase the amount of jetting of gas as much as possible while restraining noise, thus allowing the exothermic body to effectively radiate heat.
