PROBLEM TO BE SOLVED: To provide a closed-type blood reservoir, and an extracorporeal blood circulation apparatus using the same, having a structure that inhibits blockage of a blood flow route by the septum. SOLUTION: The closed-type blood reservoir includes an outer shell 1 that is formed by joining: a first joining part 6a of a blood storage chamber shell 11a, which has a curved shape that is outwardly convex; and a second joining part 6b of a volume adjustment chamber shell 11b, which also has a curved shape that is outwardly convex. The outer shell 1 contains within it a space of substantially rotated oval-shape. The blood storage chamber shell 11a is provided with a blood inlet port 4 for introducing blood, a blood outlet port 5 for discharging blood, and a blood storage chamber air discharge port 9. These are in communication with a blood storage chamber 1. The volume adjustment chamber shell 11b is provided with a volume adjustment liquid port 8 for introducing and discharging a volume adjustment liquid, and a volume adjustment chamber air discharge port 10. These are in communication with a volume adjustment chamber 2. COPYRIGHT: (C)2011,JPO&INPIT
