Focusing on the fact that fuel consumption can be improved by heating the fuel, provided is a fuel consumption improvement device for an internal combustion engine, said device increasing the efficiency of heat exchange from a fuel source to a fuel pipe which heats or cools fuel by changing the shape of the pipe, and thus achieving improved fuel consumption with a simple construction. The fuel consumption improvement device for an internal combustion engine is interposed in a fuel supply path between a fuel tank and the combustion part of the engine, regulates the temperature of fuel pumped from the fuel tank, and then supplies the fuel to the combustion part of the engine to improve fuel consumption for the engine. A portion of a fuel pipe that has good thermal conductivity and that passes through the interior of the fuel consumption improvement device is formed in a crushed shape, and the device is equipped with a temperature control means which heats or cools the vicinity of the portion with the crushed shape.
