PROBLEM TO BE SOLVED: To provide an electrode device or the like capable of reducing arc by discharge, increasing the energy of pressure waves generated by the discharge and efficiently sterilizing a sterilization object. SOLUTION: The electrode device includes: a discharge electrode part 6 comprising positive and negative electrodes 4;5 arranged at an interval g; nonelectrolyte liquid 7; and a container (airtight container 8) for storing the nonelectrolyte liquid 7 and holding the discharge electrode part 6 in the state of being positioned in the nonelectrolyte liquid 7. Also, the discharge electrode part 6 and the container (airtight container 8) storing the nonelectrolyte liquid 7 are put in liquid 41, a voltage is applied to the electrodes 4;5 of the discharge electrode part 6 to generate discharge between the electrodes 4;5, and bacteria in the sterilization object are sterilized by the pressure waves generated by the discharge.
