PROBLEM TO BE SOLVED: To provide a method of designing a heating device capable of designing a coil layout and a voltage setting for generating a nearly ideal heat-generation distribution which is made by only an electromagnetic field analysis, if a target temperature distribution is predetermined and a heat flow analysis is first done only once concerning the methods of designing and most properly operating the heating device. SOLUTION: The method comprise the steps of a first step wherein a target temperature distribution on the inner surface of an object to be heated is predetermined for designing a heating device, which heats a hollow object by induction heating and in which fluid exists in the hollow object; a second step wherein the target temperature distribution is used as one condition of heat flow analysis, and then a heat flux distribution is calculated; a third step in which a profile of the heat flux distribution is converted to a profile of a heat-generation density distribution; a fourth step in which a heat-generation density distribution is calculated by an electromagnetic field analysis; and a fifth step in which the heat-generation density distribution obtained in the third process and the heat-generation density distribution obtained in the fourth step are compared, a condition in the fourth step is revised based on the compared result, and then an induction heating condition is determined.
