To efficiently and stably generate alkaline water and acidic water by electrolysis, to improve long-term reliability and to improve washing performance.

In the washing equipment provided with an electrolysis device 19, a plurality of first and second division chambers 26 and 27 are formed by partitioning an electrolysis tub 21 constituting the electrolysis device 19 by a partition wall 24 and at least a pair of first and second electrodes 28 and 29 are disposed at the division chambers 26 and 27. Also, the partition wall 24 is formed of a non-conductive and non-water-permeable material and a communicating path 25 connecting the respective division chambers 26 and 27, through which liquid can be moved, is provided on the upper part of the partition wall 24.
