The present invention relates to a heat detecting device of a train wheel bearing, which comprises: a thermoelectric element which is in contact with a train wheel bearing to convert heat generated in the wheel bearing to electric energy; a capacitor which is electrically connected to the thermoelectric element to store the electric energy generated in the thermoelectric element; and a heat warning unit which is supplied with the electric energy from the capacitor to display a change in a temperature of the wheel bearing to the outside.
