Abstract
An endoscope is provided which includes a viewing head in a section which is insertable into a cavity of a living body. An image sensor for generating a video signal which in turn is transmitted to a television display to be visualized thereon as a television picture is provided in the viewing head. The image sensor with a shape such as a plate is located in a plane containing the longitudinal center line of the viewing head. A heat conductive material is provided in a space formed between a metal barrel of the insertable section and the plate-shaped image sensor provided in the metal barrel. With this arrangement, heat accumulated in the image sensor can be emitted to the outside.
