PURPOSE: A level gauge of a refrigerator is provided to enable a user to precisely and immediately recognize the inclination of a product by displaying a level state of the refrigerator through the electric chemical reaction of an electrode by emitting light. CONSTITUTION: A semi-circular container(14) is attached to a position demanding to keep a level state so as to sense the level state of a product through the electric chemical reaction of an electrode according to movement of bubbles(16). An electrolyte(15) is filled in the container to form the bubbles on a top end of the container in a level state. When the bubbles are on the top end, a level detection unit(13) generates electric chemical reaction through the electrolyte and sends electricity to a level display unit(20). Herein, the level detection unit consists of anode and cathode plates(17,18). Then, the level display unit displays the level state through electricity generated from the level detection unit.
