Abstract
The present invention is to provide a camera head capable of efficiently radiating heat generated by heat sources in the camera head even if it is equipped with a dust-proofing and drip-proofing structure. A heat radiating member having a higher heat conductivity than the heat conductivity of the lens barrel is disposed farther backward in the direction of the optical axis than the lens barrel. Heat generated in a CPU is transferred to the heat radiating member through a mount section, and heat generated in a CCD is transferred to the heat radiating member through the lens barrel. Since the outer circumference of the heat radiating member is always in contact with the external atmosphere, it is maintained at the temperature level of the external atmosphere, and the heat generated in the CPU and the CCD is efficiently radiated into the outer space.
