PROBLEM TO BE SOLVED: To provide a removal blood pressure measuring system for a hemodialyzer capable of easily, accurately and quickly measuring a removal blood pressure of a primary side of a blood pump. SOLUTION: This removal blood pressure measuring system for the hemodialyzer is provided with a replacement fluid injection means injecting a replacement fluid into a blood passage in the upstream side of the blood pump, a pressure detecting means detecting a pressure of the blood passage in the upstream side or the downstream side of a hemodialysis element, an actual blood flow rate computing means calculating the actual blood flow rate in the hemodialysis based on the set blood flow rate of the blood pump and detected pressures by the pressure detecting means before and after injecting the replacement fluid into the blood passage by the replacement fluid injection means, and a removal blood pressure deriving means, based on the actual blood flow rate calculated by the actual blood flow rate means, finding the removal blood pressure from the relation between the prefound actual blood flow rate or a value derived therefrom and the removal blood pressure.
