PROBLEM TO BE SOLVED: To provide a heat exchanger that prevents deformation of members and is reduced in the size thereof.SOLUTION: In a heat exchanger 1, tubes 8 through which a first medium flows are arranged in parallel and a flow channel 40 through which a second medium flows is formed between the tubes 8 adjacent to each other so that heat is exchanged between the first and second media. The heat exchanger includes: holding members 2, 3 in which a groove part 21 is formed along a longitudinal direction of the tube 8 and an end part of the tube 8 is inserted into the groove part 21 to hold the tube 8; and a sealing member 5 for sealing the flow channel 40 on a side of the end part in the longitudinal direction to prevent the second medium from leaking from the flow channel 40. |
