There is provided a method for plasma heat treatment that can suppress the degradation of thermal efficiency even in the case where plasma is used to heat a sample at a temperature of 1,200° C. or more. In a method for plasma heat treatment that a sample to be processed is heated by plasma, the method including the steps of: preheating in which a heat treatment chamber is exhausted while preheating an upper electrode and a lower electrode using plasma generated between the upper electrode and the lower electrode; and heat treatment in which the sample to be processed is heated after the preheating step. The upper electrode and the lower electrode are electrodes containing carbon.
