PURPOSE: An electrolytic cell for a precious metal recovery apparatus is provided to precisely recover precious metal from high- and low-concentration aqueous solution by electrodepositing the aqueous solution on a plurality of cathode members successively. CONSTITUTION: An electrolytic cell for a precious metal recovery apparatus comprises an electrolytic bath(10), a plurality of anode members(20), a plurality of cathode members(30), and a plurality of fixing elements(31). The electrolytic bath comprises an anode plate(11), a cathode plat(12), an inlet(13), and an outlet(14). Aqueous solution is drawn in or out through the inlet and the outlet. The plurality of anode members are arranged inside the electrolytic bath as being connected to the anode plate and divide the inside of the electrolytic bath into a plurality of chambers from one side to the other side. The plurality of cathode members are accommodated in the chambers except for the first and the last chambers and connected to the cathode plate. The plurality of fixing elements detachably mount the respective cathode members in the electrolytic bath.
