And an O-ring 4 for preventing water leakage to the outside of the electrolytic cell. A raw water inlet 5 for introducing raw water into the electrolytic cell is provided at the lower side of the electrolytic cell case 1, and an alkaline ionized water discharge port 6a and an acidic ionized water are provided at the upper side. A discharge port 6b is provided.

In the electrolytic cell case 1, a pair of divided electrolytic cell cases 1a and 1b which are divided into two parts are integrally injection-molded using a thermoplastic synthetic resin, for example, ABS resin. Then, along with this injection molding, the divided electrolytic cell case 1
The minus electrode 2a is fixed to the inner surface of a and the plus electrode 2b is fixed to the inner surface of the divided electrode case 1b.

A specific molding method of the electrolytic cell case 1 will be described below with reference to FIG.
