摘要
The present invention provides a metal plate for heat exchange which facilitates nucleate boiling and is extremely excellent in heat conductivity. In the metal plate for heat exchange of the present invention, a recess part 2 having a depth of 5 µm or more and 10% or less of a plate thickness of the metal plate is formed. A crevasse part 7 is formed at least at a bottom corner 6 of the recess part 2. The crevasse part 7 is formed by cutting away the bottom corner 6 of the recess part 2 in the thickness direction. An angle θ formed by one cut-away surface and the other cut-away surface is 90 degrees or less. In addition, the crevasse part 7 is formed by cutting away a crystal grain 9. The recess part 2 is formed on the surface of the metal plate 1 by pressing a working part 14 formed on a surface of a working roll 12 against the surface of the metal plate 1 being carried.
