PROBLEM TO BE SOLVED: To impart strength properties close to a human bone, to secure sufficient bonding properties to the bone even while avoiding the occurrence of a stress shielding phenomenon, and to maintain stable strength even to an unexpected load.SOLUTION: In a porous implant material, a plurality of metallic bodies having different porosity are joined. The high-porosity metallic body is a porous metallic body having a three-dimensional mesh-like structure wherein a plurality of pores formed by a continuous framework are communicated, and the porosity is 60-98%. The low-porosity metallic body is a dense metallic body having the porosity of 0-50%. The dense metallic bodies have: dense metallic bodies extending along an axial direction parallel to one direction and a plate-like dense metallic body extending such that the metallic body crosses the whole region along a direction orthogonal to the one direction. A thickness of the plate-like dense metallic body is 5-75% of the whole thickness, and a longitudinal elastic modulus when having been compressed in a direction parallel to the one direction is 5-35 GPa.
