PROBLEM TO BE SOLVED: To provide an electrode-cleaning apparatus that can simplify a configuration, can reduce costs, can be miniaturized, can be made inexpensive, and has improved maintenance properties. SOLUTION: The electrode-cleaning apparatus for cleaning an electrode in a measurement channel comprises: the measurement channel that is provided in a perpendicular direction while measurement fluid flows from an upper direction to a lower one; a nozzle that is provided in the middle of the measurement channel for injecting the measurement fluid from the lower portion of the measurement channel to the upper direction; a measurement electrode that is provided at the measurement channel while the electrode surface is arranged opposite to the injection orifice of the nozzle; and a plurality of beads that are provided between the injection orifice of the nozzle and the electrode surface of the measurement electrode and come into contact with the electrode surface of the measurement electrode due to the injection of the measurement fluid from the nozzle for washing the electrode surface.
