PROBLEM TO BE SOLVED: To provide a blood purifying device capable of suggesting ways for excellent blood purification even if the recirculation of blood is generated because the flow rate of the blood flowing in an access region of a patient is smaller than the quantity of the extracorporeally circulated blood; and a method of computing the recirculation rate of the device. SOLUTION: The blood purifying device has an arithmetic operation means 11 capable of computing the recirculation rate, a rate of the quantity of the recirculated blood returned from a vein side blood circuit to the patient to be guided to flow to an artery blood circuit to the quantity of the extracorporeally circulated blood, by applying a prescribed mark to the extracorporeally circulated blood and detecting the mark. The blood purifying device also has a computing means 12 capable of computing an ideal quantity of the extracorporeally circulated blood so that the recirculation rate is not more than a prescribed value if the recirculation rate computed by the arithmetic operation means 11 is at least the prescribed value.
