1. An endoscope comprising:
- an image sensor and a flexible portion having forward end, said image sensor being located in said forward end, whereby said image sensor produces a video signal which can be used to recreate a picture of an object of interest;
a tubular metal barrel forming said forward end portion of the endoscope;
an image sensor plate disposed on a plane which intersects a center axis of said tubular metal barrel, said image sensor being located in the tubular metal barrel; and
a heat conductive material interposed between said image sensor plate and said tubular metal barrel.

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.
