To provide a heat radiation device that has high mechanical strength and can appropriately protect a circuit board from vibration, and a power generation apparatus using the heat radiation device.SOLUTION: A heat radiation device includes an installation surface 210 on which an object (thermoelectric converter 30) to be cooled is installed, a heat radiating part 220 provided on a surface opposite to the installation surface 210, and an accommodation part 230 that is integrally provided on a side of the heat radiating part 220 for accommodating a circuit board 60. The heat radiating part 220 is composed by integrally forming at least two first heat radiating walls 220a and second heat radiating walls 220b, in which the first heat radiating walls rise up from the surface opposite to the installation surface 210 and face each other, and the second heat radiating walls connect the first heat radiating walls 220a facing each other. The accommodation part 230 has at least two inner surfaces 230a, 230b, 230c facing two surfaces of the accommodated circuit board 60, respectively.SELECTED DRAWING: Figure 1 【課題】高い機械的強度を有するとともに、回路基板を振動から適切に保護することが可能な放熱装置および当該放熱装置を用いた発電装置を提供する。【解決手段】放熱装置は、冷却対象物（熱電変換器３０）が設置される設置面２１０と、設置面２１０の反対側の面に設けられた放熱部２２０と、放熱部２２０の側方に一体的に設けられ回路基板６０を収容するための収容部２３０と、を備える。放熱部２２０は、設置面２１０の反対側の面から立ち上がり、互いに対向する少なくとも２つの第１放熱壁２２０ａと、互いに対向する第１放熱壁２２０ａを連結する第２放熱壁２２０ｂとが、一体形成されて構成される。収容部２３０は、収容された回路基板６０の２つの表面にそれぞれ対向する少なくとも２つの内側面２３０ａ、２３０ｂ、２３０ｃを有する。【選択図】図１
