A heat exchanger is provided to facilitate the installation work of heat exchange plates by forming a fixing member used for fixing edges of the heat exchange plates to each other. A heat exchanger(100) comprises a plurality of heat exchange plates(120) that are stacked up against each other while overlapping each other. Edges of the heat exchange plates are welded to each other to form a group, thereby forming a heat exchange part(110). A fixing member(130) is installed inside the heat exchange part and provided in a ring shape having a C-shaped cross section. An opening of the fixing member is opened to the outside of the heat exchanger. A corner of the fixing part is rounded. Adjacent heat exchange parts stuck to each other is welded in an adhesion part. Cover members(101a) coming into contact with the heat exchanger is welded to a contact part of a case(102). |
