As a result, an electrolysis reaction occurs, and silver ions (Ag +) are eluted into water from the silver ion eluate 5 la of the first chamber 32 a 1 serving as the anode.
- each silver ion eluate 51a is constantly rotating and moving, so that the anode and the cathode are close to each other on both sides of the window 32c. Moments are not always kept. However, since the silver ion eluate 5 la is moved away from the window 32 c because the silver ion eluate 5 la is constantly rotating and moving, the next silver ion eluate 51 a is directly in the window 32 c. Approaching is repeated. Therefore, in a state where the silver ion eluate 51 a is stirred in the first chamber 32 al and the second chamber 32 a 2, the silver ion eluate 51 a serving as the anode through the window 32 c is stirred. The state in which the silver ion eluate 51a as the cathode is in close proximity is sufficiently ensured, and as a result, elution of silver ions by electrolysis is obtained. '

Fixing is prevented. The fact that the state where the deposit is hardly fixed is maintained, which means that there is almost no need to replace the silver ion eluate 51a with the decrease in the silver ion elution effect of the deposit. Substantially, it is only necessary to replace the silver ion eluate 51 a when the silver portion of the eluate 51 a is significantly worn and the silver ion elution effect is reduced.
