For example, in the main heat transfer surface portion (2a) where the angle (θ) of the waveform (5) is large, the triangular dam portion (2b) with low flow resistance is suitable, and when the angle (θ) of the waveform (5) is small. In the heat transfer surface portion (2a), the triangular weir portion (2
