The object of the invention is to provide a water supply controlling method of a high-frequency heating apparatus and the high-frequency heating apparatus wherein water supplied to a heating chamber as steam is controlled in the quantity and the quality and power can be saved. To achieve the object, it is judged whether there is the required quantity of water supplied as steam in cooking in a water tank or not and in case it is judged that the water is short, request for replacing water in the water tank is annunciated. Elapsed time since water in the water tank was last replaced is monitored and in case the elapsed time exceeds predetermined time, request for replacing the water is annunciated.
