<P>PROBLEM TO BE SOLVED: To provide a fuel consumption notifying device for determining the quality of fuel consumption corresponding to an operation quantity to a vehicle with a simple constitution. Ž<P>SOLUTION: An eco-drive indicator 100 has a display control circuit part 20 for acquiring information on a speed of the vehicle and information on the fuel consumption as a speed value Snow and a fuel consumption value Anow, calculating a determining fuel consumption value Ajudge being a reference of determining the quality of the fuel consumption value Anow and generating a determining result by determining the quality of the fuel consumption by comparing this determining fuel consumption value Ajudge with the fuel consumption value Anow, and an eco-lamp 13e for notifying the determining result. The display control circuit part 20 has an external storage device 21c for storing a plurality of preset reference speed values and reference fuel consumption values, and selects the reference speed value for forming a section including a speed value Snow from the plurality of reference speed values, and calculates the determining fuel consumption value Ajudge corresponding to the speed value Snow by linearly interpolating the reference fuel consumption valve corresponding to this reference speed value.
