する角度可変液体識別センA liquid is brought into contact with the outside of the total reflection surface of an optical prism, a light beam obtained by an optical system including an optical fiber and a lens is projected onto the total reflection surface at a desired angle of incidence, and the reflected light beam is focused by the lens. In a liquid identification sensor that identifies the liquid by outputting it to the outside through an optical fiber and monitoring the intensity of the output light to determine whether the reflection is total reflection, and the integrated structure is configured to be able to be displaced parallel to the incident plane of the light beam so that the incident angle changes around the area where the reflection occurs. liquid identification sensor
