Abstract
A vehicle heat exchanger includes a plurality of cup plates that are formed such that a first layered space into which a first heat carrier is introduced and a second layered space into which a second heat carrier is introduced are formed alternately between the plurality of cup plates when the plurality of plates are stacked. Peripheral end portions of the plurality of cup plates are fixed together in a liquid-tight manner. A distance in a stacking direction from a first cup plate that forms the first layered space to a second cup plate that forms the second layered space and a distance in the stacking direction from the second cup plate to the first cup plate are set to different distances, and end portions of outer wall portions of the cup plates are bent back so as to be apart from each other when the cup plates are stacked.
