PURPOSE:To perform color image pickup good in picture quality by preventing the transfer of heat due to heating at a peripheral circuit substrate to a solid state image sensor with an adiabatic member and radiating the heat self-radiated of the sensor to a cabinet by a Peltier element. CONSTITUTION:At each CCD image sensor 2r, 2g, or 2b, each end part of a heat radiating member 7 having a small heat resistance which is performed in almost a T-character shape is fixed in a state that it contacts in whole plane with the back plane of each package. The heat radiating member 7 is arranged in such a way that the center part of it is to be faced with a heat radiating metallic parts 11 made of alminum which is provided at a cabinet 4. And a Peltier element 10 is provided between the center part of the heat radiating member 7 and the heat radiating metallic parts 11 provided at the cabinet 4. Furthermore, an adiabatic member 8 having a large heat resistance, such as a synthetic resin sheet,etc., is provided so as to cover a color separation prism 1 mounted at the cabinet 4 and each CCD sensor and a peripheral circuit substrate 9 is arranged with putting the adiabatic member 8 between.
