PURPOSE:To increase a heat transfer rate to from an air side as well as increase a heat transfer area by constructing a heat exchanger by incorporating therein resin-made fine diameter hollow fibers. CONSTITUTION:A heat exchanger 2 is constructed such that many resin-made fine diameter (outer diameter several hundred mm - several mm for example) hollow fibers 21 are braided into braided pairs 20 of a substantially plate shape, and opposite ends of the braided hollow fibers 21, 21,...are tied up, heat-melted, and united together, which are fixedly connected with a pipe end fitting 22. Accordingly, the respective hollow fibers 21, 21,... are opened uniformly in the pipe end fitting 22. Hereby, refrigerant (water) can be supplied from one pipe end fitting 22 side toward the other pipe end fitting 22 side, during which heat exchange is performed between the water flowing through the respective hollow fibers 21, 21,...and air flowing outside the hollow fibers.
