Abstract
A heat exchanger includes a core unit having a plurality of pipe members open at opposite ends and arranged in parallel, a pair of tanks joined to the core unit to sandwich the core unit from opposite sides in a longitudinal direction of the pipe members and communicating with the pipe members, and a partition plate for closing a cross-section of the tank intersecting with a pipe member arrangement direction. A pair of projections for sandwiching the partition plate from opposite sides in the pipe member arrangement direction is provided on an inner wall surface of the tank. The projections are formed by plastic working parts of the tank at opposite sides of a part to be held in contact with the partition plate in a direction at the pipe member arrangement direction from an outer side toward an inner side of the tank.
