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 according to the present invention has a plurality of porous metal bodies 4 which are bonded with each other at bonded-boundary surface F parallel to a first direction, wherein each the porous metal body has a three-dimensional network structure formed from a continuous skeleton 2 in which a plurality of pores 3 are interconnected, a porosity rate is 50% to 92%, and a compressive strength compressing in a direction parallel to the bonded-boundary surface F is 1.4 times to 5 times of a compressive strength compressing in a direction orthogonal to the bonded-boundary surface F.
