Providing porous implant material having a strength property approximate to human bone, without arising stress shielding, and which is possible to maintain sufficient bound strength with human bone. Porous implant material has a porous metal body having a three-dimensional network structure formed from a continuous skeleton 2 in which a plurality of pores 3 are interconnected, wherein a porosity rate is 50% to 92%, the pores 3 are formed to have flat shapes which are long along a front surface and short along a direction orthogonal to the front surface, lengths Y of the pores 3 along the front surface are 1.2 times to 5 times of a length X orthogonal to the front surface, and a compressive strength compressing in the direction parallel to the front surface is 1.4 times to 5 times of a compressive strength compressing in the direction orthogonal to the front surface. |
