PROBLEM TO BE SOLVED: To provide an oral cavity washing device that can suppress dispersion of a washing fluid.SOLUTION: An oral cavity washing device comprises: a washer body part having a water storage tank for storing a washing fluid for washing an oral cavity; a nozzle body part 20 having a nozzle grip part 21 and an injection nozzle part 22; and a driving part 60 for causing the injection nozzle part 22 to be driven to perform injection. The oral cavity washing device has a tank internal electrode 40 formed in the water storage tank and a grip part electrode 41 formed in the nozzle grip part 21. The driving part 60 controls the driving part 60 according to an inter-electrode resistance change detected between the tank inner electrode 40 and the grip part electrode 41. |
