Abstract: A heat dissipation structure includes a ceramic substrate having an insulation quality, a metal member containing a metal or an alloy and joined to a surface of the ceramic substrate by a brazing material, a metal film layer formed by accelerating a powder containing a metal or an alloy with a gas and by spraying and depositing the powder in a solid phase state on a surface of the metal member, and a heat pipe that is in a rod shape and capable of controlling a temperature and comprises a heat absorbing unit configured to absorb heat from outside at one end of the heat pipe and a heat dissipating unit configured to dissipate heat to the outside at another end of the heat pipe, wherein the heat absorbing unit is embedded inside the metal film layer.
