Abstract
A fuel property detection device for detecting a property of fuel based on a detection signal output from a photoreceptor includes a light guiding member having a reflecting surface located in direct contact with the fuel. The light guiding member includes a light emitting surface through which measurement light from a light source is emitted from the light guiding member into the fuel, a light incident surface through which the measurement light emitted from the light emitting surface and passing through the fuel enters again the light guiding member, and the reflecting surface from which the measurement light incident from the light incident surface is reflected toward the photoreceptor. The light incident surface and the light emitting surface are opposite to each other to have a space therebetween in the light guiding member, and the space is provided to be filled with the fuel.
