Abstract:
1. An electrodeposition tank which circulates a processing solution, the electrodeposition tank circulating the processing solution in a first direction at an upper part of the electrodeposition tank and circulating the processing solution in a second direction opposite to the first direction at a lower part of the electrodeposition tank to generate an agitating flow, the electrodeposition tank comprising: at least one of a guide plate, located at an end of the electrodeposition tank which is downstream from a part of the processing solution flowing in the first direction, which reverses a flow of the processing solution by directing the flow of the processing solution towards a bottom of the electrodeposition tank, and a guide plate, located at an end of the electrodeposition tank which is downstream from a part of the processing solution flowing in the second direction, which reverses the flow of the processing solution by directing a flow of the processing solution toward a surface of the processing solution, wherein each guide plate has a substantially arcuate shape.
