Abstract (en)

This copper porous body for vaporization members is a copper porous body for vaporization members used as a vaporization member which vaporizes a liquid phase medium that comes into contact with the vaporization member, the copper body is composed of a sintered body of a plurality of copper fibers, and has a stem having a three-dimensional network structure. A porosity is in a range of 65% or more and 95% or less, an opening diameter is in a range of 100 µm or more and 2,000 µm or less, and a standardized specific surface area S<sub>D</sub>= S × R defined as a product of a specific surface area S (m<sup>2</sup>/g) and a diameter R (m) of the copper fiber is in a range of 0.001 or more and 0.25 or less.
