Claim 18:
19. A storage medium storing a calculation program that performs a process of controlling a supply power to a heater of a mounting table including the heater configured to adjust a temperature of a mounting surface on which a consumable part that is consumed by plasma processing is mounted such that the heater reaches a setting temperature, measuring the supply power in a non-ignition state in which plasma is not ignited and the supply power in an ignition state after the plasma is ignited, and calculating a thickness of the consumable part by using a heat input amount from plasma to the consumable part, a thermal resistance between the consumable part and the mounting surface, the thickness of the consumable part as parameters, and by using the measured supply power in the non-ignition state and the measured supply power in the ignition state.
