An object of the present invention is to provide a sterilization method capable of reliably killing bacteria and molds to be sterilized and capable of reducing running costs. A sterilization step of supplying a peracetic acid-based disinfectant containing hydrogen peroxide to sterilize at least an inner surface of the container; and a rinsing step of supplying aseptic water to wash away at least the peracetic acid-based disinfectant in the container. The sterilization step and the rinsing step are performed according to the following. That is, in the sterilization step, the concentration of hydrogen peroxide (H 2 O 2 ) in the peracetic acid-based disinfectant is maintained at 300 ppm or less, preferably 200 ppm or less, and the temperature of the peracetic acid-based disinfectant is 50 ° C. or less. . In the rinsing step, sterile water of 65 ° C. or higher is used. [Selection] Figure 1 |
