特徴とするアルコール含有率センサ。[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 detection light incident on the fuel passage is reflected by the reflective surface of a reflective member provided in the fuel passage, and then made incident on the refracting surface again.
In an alcohol content sensor that detects the content of alcohol contained in fuel by making this detection light enter the optical position detection element, the reflecting member is made of a substrate made of synthetic resin and a nickel plating plated on the substrate. An alcohol content sensor characterized in that the surface of the plating layer is then polished to form a reflective surface, and the reflective surface is disposed to face the refractive surface.
