PROBLEM TO BE SOLVED: To provide a blood port and a blood processing device using the blood port which can prevent blood from staying in the blood port by making the radius of a fillet in the crossing line of the inside of a blood intake and the blood port shorter than a prescribed dimensions, and which can reduce the possibility of activation of coagulation factors and heunopexis due to the staying blood and the possibility of generation of hollow fibers which stop blood flow. SOLUTION: In this blood port 1 with a blood intake 3, the radius R of a fillet attached in the crossing line of the inner surface ' of the blood intake 3 and the inner surfaceγof the blood port 1 is to be shorter than 4mm. The blood processing device has this blood port 1. A bundle of hollow fibers is fixed at the housing of the blood processing device, and the blood port 1 with the blood intake 3 is attached on the surfaceαof the edge of the bundle of hollow fibers.
