Abstract
To provide a sensor-equipped hood capable of detecting force applied to the hood without narrowing an operating field viewed through the hood. A sensor-equipped hood protrudes from a tip end portion of an endoscope main body, and is attached to the tip end portion. The sensor-equipped hood includes a transparent tubular hood main body and a fiber Bragg grating (FBG) sensor fixed to a first fixing point of the hood main body and having a Bragg grating. In the FBG sensor, the wavelength of reflected light at the Bragg grating changes based on fluctuation of the first fixing point in the hood main body.
