ABSTRACT:
A portable endoscope having a control part containing an entrance end portion of a light guide for transmitting light for illuminating an object, and a hermetic illuminating light supply unit containing a light source lamp for supplying illuminating light to the light guide. The unit is connected to the control part. An armoring member is disposed at a position where it is heated by heat radiated from the light source lamp. The outer surface of the armoring member is covered with a heat-insulating cover made of a material having a low thermal conductivity. A battery chamber is formed in the illuminating light supply unit to accommodate a battery as a power supply for the lamp. A relief valve releases the pressure in the battery chamber to the outside of the unit when the pressure rises.
