PROBLEM TO BE SOLVED: To provide a method and a device for detecting outpouring of slag used for a continuous casting machine equipped with a sliding nozzle, capable of preventing detecting errors caused by opening and closing of the sliding nozzle, and which can detect outpouring of slag without delay of detection. SOLUTION: The device to detect outpouring of slag, installed to the continuous casting machine equipped with the sliding nozzle 1b, starts detection operation of outpouring slag when a remaining quantity of molten metal in a ladle 1 reaches a predetermined level, detects a pressure of an inert gas filled in a feed nozzle 4 which conducts molten metal W from the ladle 1 to a tundish 2 by preventing opening and closing movements of the sliding nozzle 1b, and determines that the slag S is outpouring if the detected pressure level is exceeding a threshold.
