Title PLASMA STERILIZATION DEVICE
Abstract Provided is a plasma sterilization device for carrying out plasma sterilization that enables homogeneous sterilization without causing deterioration in quality by preventing damage under mild conditions, even for sterilization targets having various three-dimensional shapes such as agricultural products. The plasma sterilization device is configured so as to be provided with: a voltage-applying means that applies a voltage to a sterilization target having conductivity; a pair of electrodes that applies, in a discharged state, the voltage applied by the voltage-applying means to the sterilization target via a dielectric; and a position-changing means that changes the relative position between the pair of electrodes and the sterilization target.
