PROBLEM TO BE SOLVED: To provide a heat exchanger, in which mixing of heat media for heat exchange is inhibited.SOLUTION: A heat exchanger includes a pair of headers 2, 3 having a tubular shape, and allowing a refrigerant to flow in the tubular shape, a plurality of tubes 4 arranged between the pair of headers 2, 3 and connected to the respective headers 2, 3, allowing the pair of headers 2, 3 to communicate each other, and a pair of plates 51 laminated between the two adjacent tubes 4 among the plurality of tubes 4 and forming a passage space where liquid can flow. The pair of plates 51 is formed with recessed parts 514 faced each other and defining the passage space, respectively, connection parts P1, P2 of the headers 2, 3 and the tubes 4 are disposed outside the passage space, a refrigerant having flown through one of the headers 2, 3 flows inside the tubes 2, 3 and flows into the other of the headers 2, 3, and the refrigerant flowing in the tubes 4 and liquid flowing in the passage space are caused to exchange heat. |
