  The first film protection unit 43 extends along the first power supply unit 36. Accordingly, contact between the diaphragm 33 and the first power feeding unit 36 is effectively avoided without increasing the area of the first film protection unit 43. Therefore, the area where the diaphragm 33 is exposed to the first electrode chamber 51 is increased, and electrolysis in the first electrode chamber 51 is promoted.

  The first film protection unit 43 is formed integrally with the first crosspiece 45 adjacent to the first power feeding unit 36. Thereby, the 1st film | membrane protection part 43 and the 1st crosspiece 45 mutually connect, and mutually increase the rigidity synergistically.

  A first groove 43 a is formed in the first film protection unit 43 along the first power feeding unit 36. Accordingly, as indicated by an arrow W1 in FIG. 7, water can flow in the first groove 43a along the circumferential direction perpendicular to the axial direction of the first power feeding unit 36. Accordingly, the retention of water due to the first membrane protection unit 43 interposed between the diaphragm 33 and the first power supply unit 36 is suppressed, the strength of electrolysis in the first electrode chamber 51 is made uniform, and the electrolytic hydrogen The dissolved hydrogen concentration in water is increased.

  The second film protection unit 44 extends along the second power supply unit 38. This effectively avoids contact between the diaphragm 33 and the second power feeding unit 38 without increasing the area of the second film protection unit 44. Therefore, the area where the diaphragm 33 is exposed to the second electrode chamber 52 is increased, and electrolysis in the second electrode chamber 52 is promoted.

  The second film protection unit 44 is formed integrally with the third crosspiece 47 adjacent to the second power feeding unit 38. Thereby, the 2nd film | membrane protection part 44 and the 3rd crosspiece 47 mutually connect, and mutually increase the rigidity synergistically. Accordingly, both the supporting action and the protecting action of the diaphragm 33 by the third crosspiece 47 and the second film protecting portion 44 are enhanced.

  A second groove 44 a is formed in the second film protection unit 44 along the second power feeding unit 38. As a result, as indicated by an arrow W2 in FIG. 9, water can flow in the second groove 44a along the circumferential direction perpendicular to the axial direction of the second power feeding portion 38. Therefore, the retention of water due to the second membrane protection unit 44 interposed between the diaphragm 33 and the second power feeding unit 38 is suppressed, the strength of electrolysis in the second electrode chamber 52 is made uniform, and the electrolysis is performed. The dissolved hydrogen concentration of hydrogen water is increased.

The fourth crosspiece 48 is formed so as to protrude toward the second main body portion 37 with respect to the second film protection portion 44.
A third groove 48 a is formed in each fourth bar 48 in a direction along the second power feeding portion 38. The third groove 48a extends so as to be aligned with the second power feeding unit 38.
