A device for indicating the level of a liquid contained in a tank. The liquid level indication device includes: a liquid level measuring unit for measuring the level of the liquid contained in the tank; an indicating unit disposed outside of the tank to indicate the level of the liquid measured by the liquid level measuring unit; and a controller for outputting to the indicating unit a control signal based on a measurement signal obtained on measurement by the liquid level measuring unit. The indicating unit is provided with a plurality of light-emitting elements which are located respectively at positions corresponding to a plurality of positions ranging from an uppermost position to a lowermost position of the level of the liquid contained in the tank. The controller causes the light-emitting elements corresponding to the liquid level measured by the liquid level measuring unit to emit light.
