PROBLEM TO BE SOLVED: To provide a heat exchanger provided with a plurality of thin tubes and base tubes disposed at both ends of the thin tubes, and performing heat exchange on surfaces of the thin tubes. SOLUTION: In this heat exchanger 2 having the plurality of thin tubes 3 in which at least one of a first heat medium 4 and a second heat medium 5 exchanging heat with each other is circulated, ends of the plurality of thin tubes 3 are bound in an air-tight state or a liquid-tight state among the thin tubes 3, and the bound thin tubes are air-tightly or liquid-tightly inserted into a plurality of cores 7 having flat shapes, and displaced from each other in a direction along surfaces of the cores 7 in a state that the cores 7 adjacent to each other vertically to the face direction of the cores 7 have a prescribed interval vertically with respect to the face direction of the cores 7.
