Abstract
An endoscope includes an image pickup unit having a solid-state image pickup device such as a CCD on a tip end side of an elongate insertion section. This image pickup unit constitutes a tip end side unit U and a rear end side unit U by conducting a surface treatment (metallization) to nonmetal members such as a tip end cover glass and a rear end cover glass and by airtight coupling surface-treated portions of the nonmetal members to metal members such as a tip end cover glass frame and a rear end cover glass frame by brazing using soldering, and constitutes an optical system unit by airtight coupling the metal members to metal members of an insulating unit U formed by airtight coupling a pipe member and a ring member to an insulating frame by welding.
