A heat dissipating apparatus and an electronic device having the same are provided. The electronic device includes a body, an internal circuit board provided in the body and including at least one heat generating element, and a heat diffusion type heat dissipating module provided in the body and stacked on a surface of the internal circuit board, so as to diffuse heat generated by the heat generating element toward a low temperature region having a temperature lower than a temperature of the at least one heat generating unit. The heat diffusion type heat dissipating module has a sheet shape which extends from the heat generating element toward a circumference surface of an inside of the body so that the heat is transferred from the heat generating element to the low temperature region.
