Abstract
An endoscope disclosed herein is provided with an operating section and an insertion section having a bending section. Bending members, which are formed of a shape memorizable alloy and are for bending the bending section, are disposed within the bending section of the insertion section and are connected to a power supply unit. This endoscope further comprises a detecting unit for detecting the amount of deformation of the bending members as a change in electric resistance, and a display device for displaying the detected amount of deformation of the bending members. Accordingly, the bending amount of the bending section can accurately be detected and displayed.
