Claims

[Claims for Utility Model Registration] A light emitting element and an optical position detection element are provided at one end of the light transmitting body, and the refracting surface at the other end of the light transmitting body is located in the fuel passage, and the light emitting element The refracted light incident on the fuel passage is reflected by a reflective surface of a reflective member provided in the fuel passage, and then made incident on the refracting surface again.
In the alcohol content sensor that detects the content of alcohol contained in the fuel by making this refracted light enter the optical position detection element, the reflecting member provided in the fuel passage is arranged so that its reflecting surface is on a vertical line. An alcohol content sensor characterized in that the alcohol content sensor is arranged at the same position.
