PROBLEM TO BE SOLVED: To provide a plasma sterilizer capable of securely and inexpensively sterilizing a treated object by generating high density oxygen radicals. SOLUTION: A storage means 1 for storing the treated object is kept under low pressure by a low pressure maintaining means 2, and oxygen gas is fed to the storage means 1 from an oxygen gas feeding means 3. Oxygen in the oxygen gas is made plasmatic so that oxygen radicals are generated. Accordingly, the oxygen radicals can be maintained as a simple substance for a long period of time and can be generated at a high density, and therefore, the treated object can be sterilized securely and inexpensively.
