The objective of the present invention is to provide a heat exchanger that can rapidly supply hot water and can be manufactured in a simple manner. The heat exchanger of the present invention comprises: a heat exchange unit (1100, 1200, 1300) in which heat is exchanged between combustion gas caused by a burner (70) for combusting a mixture and first/second heating mediums, and heating medium flow channels through which the first/second heating mediums flow and a combustion gas flow channel through which the combustion gas flows are alternately formed adjacent to each other in spaces between a plurality of plates (110, 120, 210, 220, 310, 320); and a combustion gas discharge unit (700) through which the combustion gas having passed through the heat exchange unit (1100, 1200, 1300) is discharged, wherein the heat exchange unit (1100, 1200, 1300) includes first to third heat exchange units (1100, 1200, 1300) integrally formed with a plate, in which the first heat exchange unit (1100) has a sensible-heat flow channel for the first heating medium that is formed between a pair of opposite plates in order to heat the first heating medium by absorbing the sensible heat of the combustion gas, the second heat exchange unit (1200) has a latent-heat flow channel for the first heating medium that is formed between a pair of opposite plates in order to heat the first heating medium by absorbing the latent heat of the combustion gas, the latent-heat flow channel communicating with the sensible-heat flow channel for the first heating medium which is formed in the first heat exchange unit (1100), and the third heat exchange unit (1300) has a flow channel for the second heating medium that is formed between a pair of opposite plates in order to heat the second heating medium by absorbing the latent heat of the combustion gas. |
