Claim 12:
13. The chemical treatment solution regeneration apparatus according to claim 10, wherein:
the flow mechanism comprises:
an under-regeneration-treatment-solution circulation channel that causes the oxalate treatment solution in the treatment solution regeneration bath to circulate;
the under-regeneration-treatment-solution circulation channel comprises:
an under-regeneration-treatment-solution circulation channel main body having two end portions, the under-regeneration-treatment-solution circulation channel main body being capable of containing one part of the oxalate treatment solution in the treatment solution regeneration bath,
an under-regeneration-treatment-solution inflow port that is formed at one of the end portions of the under-regeneration-treatment-solution circulation channel main body, and that allows the oxalate treatment solution in the treatment solution regeneration bath to flow into the under-regeneration-treatment-solution circulation channel main body,
an under-regeneration-treatment-solution discharge port that is formed at the other end portion of the under-regeneration-treatment-solution circulation channel main body, and that discharges the oxalate treatment solution in the under-regeneration-treatment-solution circulation channel main body into the treatment solution regeneration bath, and
an under-regeneration-treatment-solution circulation driving source that causes the oxalate treatment solution in the under-regeneration-treatment-solution circulation channel main body to move from the under-regeneration-treatment-solution inflow port to the under-regeneration-treatment-solution discharge port; and
at least one of the light source members is disposed between the under-regeneration-treatment-solution inflow port and the under-regeneration-treatment-solution discharge port.
