PROBLEM TO BE SOLVED: To provide a blood inflow port having a small blood filling amount and a small pressure loss in the blood circulation. SOLUTION: The blood inflow port 20 is provided with a first tube section 21 connected to an extracorporeal blood circulation circuit, a second tube section 22 connected to the blood storage tank and a probe insertion section 25 for inserting a temperature probe. The probe insertion section is connected to a connection section between the first tube section and the second tube section, the first tube section adjacent thereto or the second tube section. When an axis in parallel to the central axis of the second tube section is defined as a Z axis, an axis orthogonally crossing with the Z axis and being parallel to a plane including the central axis of the first tube section and the central axis of the second tube section is defined as an X axis, and an axis orthogonally crossing with the X axis and the Z axis is defined as Y axis, a shape formed by the inner wall face of the second tube section in the cross section being in parallel to an XY plane in the position where the probe insertion section is connected or a position adjacent thereto is an approximately elliptical shape whose long axis direction is in parallel to the X axis.
