A heat exchanger is provided to prevent a welding portion of a heat exchange plate from being damaged by supporting an edge of the heat exchange plate using a fixing member. 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). Inner heat exchange plates face to each other. Outer heat exchange plates are provided at an edge thereof with a stepped portion, so that the inner heat exchange plates are mounted on the stepped portion. A fixing member(130) is mounted inside the heat exchange part. The fixing member is 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. |
