PROBLEM TO BE SOLVED: To provide a decontamination method and a decontamination apparatus each capable of effectively performing the deposition prevention, growth prevention, or removal of contaminants with little thermal energy consumption. SOLUTION: The decontamination method prevents the deposition or growth of a solid compound as a contaminant on the inside wall surface of a passage constituent, such as a reaction tank, a crystallizer, a pipe, a liquid pumping machine, a heat exchanger, or a valve, where a reaction product fluid W transfers, or removes the solid compound deposited on such surface as a contaminant. The prevention of the deposition of a contaminant or the removal of a deposited contaminant is performed by intermittently heating the passage constituent by using a heating means 2 formed on the outside wall of the passage constituent during the transfer of the reaction product fluid W.
