A porous living body repairing member obtained by compressionmolding a metal fiber material into a desired shape, sintering the fiber mesh body, or thereafter, imparting a compressive stress of not more than 4.00 to 40.0 MPa to provide a porous living body repairing member having a compressive elasticity of not more than 2000 MPa and a permanent deformation of not more than 1 % under a stress below the compressive yield stress. When the porous living body repairing member is used at a high compressive load site such as man's lumbar body, permanent deformation hardly occours. When said member is transplanted within the living body, its stress to the bone is well transmitted, and it acts advantageously to the bone ingrowth in the pore. At the same time, bone absorption around the repairing member is not developed.
