摘要

This porous copper body includes: a skeleton which is formed of a sintered body of a plurality of copper fibers and has a three-dimensional network structure, wherein the copper fibers forming the skeleton consist of copper or a copper alloy, and the copper fibers have a diameter R in a range of 0.01 mm to 1.0 mm, a ratio L/R of a length L to the diameter R in a range of 4 to 200, and a circularity of a cross section orthogonal to a length direction in a range of 0.2 to 0.9, and the porous copper body has a porosity of 50% to 95%.
