摘要
A porous copper sintered material (10) includes: a plurality of copper fibers (11) sintered each other, wherein the copper fibers (11) are made of copper or copper alloy, a diameter R of the copper fibers (11) is in a range of 0.02 mm or more and 1.0 mm or less, and a ratio L/R of a length L of the copper fibers to the diameter R is in a range of 4 or more and 2500 or less (11), redox layers (12) formed by redox treatment are provided on surfaces of copper fibers (11, 11), and concavities and convexities are formed by the redox layer (12), and each of redox layers (12, 12) formed on each of the copper fibers (11) is integrally bonded in a junction of the copper fibers (11).
