A heat exchanger for an oxygenator device has multiple hollow fiber membranes that each have a hollow portion through which a heat medium passes, wherein the fibers are wound as a cylinder body. Each of the hollow fiber membranes follows a path between opposing ends of the cylinder body which is tilted with respect to a central axis of the cylinder body and is wound around the central axis of the cylinder body, wherein a tilt angle θ with respect to the central axis ranges from 22° to smaller than 67°, and wherein a constituent material of each of the hollow fiber membranes has a Young's modulus E ranging from 2.6 GPa to 0.07 GPa. During winding, the hollow fiber membranes are stretched according to a stretching rate between 0.5% and 3.0% and then fixed at the ends to maintain the stretching.
