Abstract

To suppress stagnation portion of blood flowing between a housing (10) and a hollow fiber membrane layer (30) and improve antithrombogenicity, an oxygenator (100) includes a housing (10) having a cylindrical shape and including a blood inflow port (14) and a blood outflow port (15), and a hollow fiber membrane layer (30) having a stacked structure obtained by winding hollow fiber membranes (31) accommodated in the housing (10), the oxygenator in which blood flowing in from the blood inflow port (12) flows from one end toward the other end in a longitudinal direction of the housing (10) and flows out from the blood outflow port, in which, in the hollow fiber membrane layer (30), a winding interval (P1) of the hollow fiber membranes wound in an outermost layer in the stacked structure is wider than a winding interval (P2) of the hollow fiber membranes in other layers.
