Abstract
An endoscope includes in the viewing head of its insertable section 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. The image sensor with a shape such as a plate is located in a plane containing the longitudinal center line of the viewing head. In the present endoscope, a prism to be cemented to the image sensor is shielded in the periphery thereof by a light shielding material except for an image pick-up light path which is so positioned as to face the image area of the image sensor, whereby any lights other than a light contributing to forming an image are prevented from entering the image sensor.
