PROBLEM TO BE SOLVED: To provide a dialysate supply device for supplying dialysate to a dialysis monitoring device for performing hemodialysis, including a liquid storing tank for storing dialysate, and two mixing tanks for mixing clear water and dialysis undiluted solution to prepare dialysate, which is adapted to supply dialysate from one mixing tank to the liquid storing tank while dialysate is prepared in the other mixing tank, reducing the volume of the liquid storing tank, thereby manufacturing the dialysate supply device itself in a small size. SOLUTION: This dialysate supply device for supplying dialysate to the dialysis monitoring device includes: first and second mixing tanks 2, 3 for mixing clear water and dialysis undiluted solution to prepare dialysate; a liquid storing tank 4 for storing the dialysate prepared in the first and second mixing tanks; and first and second three-way valves 21, 22 as valve means provided between the first and second mixing tanks and the liquid storing tank. When the valve means are switched to communicate the first mixing tank and the liquid storing tank with each other, the liquid storing tank enters a full-load state, so that the dialysate is stored extending over the liquid storing tank, a first supply passage and the first mixing tank. After that, when the first mixing tank becomes empty and the dialysate in the liquid storing tank is decreased to a predetermined quantity, the valve means are switched to communicate the second mixing tank with the liquid storing tank.
