Abstract: An object is to provide a blood purifying device and an access flow rate measuring method enabling easy and accurate measurement of an access flow rate of an access vessel. A blood purifying device includes a flow rate calculating unit calculating the access flow rate of an access vessel based on an initial blood indicator for blood distributed through a vein side circuit and flowing through the access vessel of a patient, the flow rate distributed through measuring means when a pump is reversed to cause the priming solution to flow out from an artery side circuit, and a blood indicator for the blood diluted with the priming solution which is obtained when the pump is reversed to dilute, with the priming solution, the blood distributed through the vein side circuit.
