Abstract
A metallic corrugated plate applying to a cooling inner fin of a heat exchanger, wherein a bending angle .THETA. of an end bent ridge portion is smaller than bending angle .theta. of the other bent ridge portions. Thus, in case the bending angle .THETA. becomes large by a resilient force after forming the bent ridge portions, preventing a bending rigidity of the end bent ridge portion in the spreading direction from being reduced is possible. Accordingly, preventing the inner fin from being warped from substantially the center ridge of the bent ridge portion is attained.
