PROBLEM TO BE SOLVED: To increase the flow speed of a heat medium liquid which flows in thin heat transfer tubes, and enhance the efficiency of heat exchange with an increase in the volume of a blood flow path minimized. SOLUTION: A bundle 2 of thin tubes which includes thin heat transfer tubes 1 is sealed by seal members 3a-3c to form a blood flow path 5 which intersects the thin heat transfer tubes. Headers 6, 7 for the thin heat transfer tubes comprise flow chambers for containing the ends of the bundle of thin tubes, and the headers have introducing and discharging ports 6a, 7a for a heat medium liquid. The bundle of thin tubes is divided in the direction of the blood flow path to form a layered structure of thin-tube bundle units 12a-12c. The flow chambers are partitioned into divided flow chambers 13a, 13b, 14a, 14b by partition walls 6b, 7b to form a flow path via which the heat medium liquid is caused to sequentially pass through each thin-tube bundle unit. The flow chambers are separated such that one thin-tube bundle unit of the thin-tube bundle units on both sides of the boundary which corresponds to each of the partition walls has an end which protrudes further toward the outside than the end of the other thin-tube bundle unit, and a side surface of the partition wall is in contact with a side surface of the protruded portion of the end.
