PROBLEM TO BE SOLVED: To provide a display method of a cooling temperature pattern in a cooling zone of a continuous heat treatment furnace for a steel sheet, in which an actual cooling rate and cooling temperature history are displayed on a display panel of an operation panel of the cooling zone, while indicated on a continuous cooling transformation diagram and can be reflected to quality management of a steel sheet coil. SOLUTION: In the display method of the cooling temperature pattern in the cooling zone of the continuous heat treatment furnace where the traveling steel sheet is subjected to the continuous heat treatment, the record values of the cooling temperature history and the cooling rate are obtained from the record values of a steel sheet size, passing speed, cooling zone inlet side sheet temperature and number of revolutions of a cooling blower, and the obtained cooling temperature history and the cooling rate are displayed on the continuous cooling transformation diagram.
