PROBLEM TO BE SOLVED: To provide a digital camera which prevents an external force applied to a casing of the camera from acting on a CCD directly, and can cool the CCD efficiently. SOLUTION: The camera casing is composed of covers 2, 3, and the CCD 17, a Peltier device 18, and a sealing member 22 are put in the camera casing. Between the Peltier device 18 and the sealing member 22, silicon grease or graphite 24 having high thermal conductivity is applied or interposed, and the sealing member 22 is fixed to a base 2A and presses the CCD 17. Between the sealing member 22 and the cover 3, a jelly-like silicon sheet 25 is interposed. The heat of the CCD 17 is absorbed by the Peltier device 18, and transmitted to the cover 3 through the sealing member 22 and the silicon sheet 25. Since the silicon grease or graphite 24, and the silicon sheet 25 function not only as heat transfer members but also as external force absorbing members for absorbing the external force acting on the CCD 17, the number of required components can be reduced, and manufacturing becomes more efficient.
