Abstract
A prosthesis for the replacement of hard tissues of human bones and joints, comprising a porous lamination component of metal thin sheets, each having a plurality of through holes and a thickness of 150 .mu.m or less, and being unharmful to the living body, the porous lamination component being formed such that the sheets are laid over one another and are then diffusion-bonded therebetween into one body by heating so that the through holes communicate with one another in the direction of the thickness thereof, and the prosthesis being entirely or partially composed of the porous lamination component. The present invention also relates to a method of making such a prosthesis. The present invention can provide prostheses which are not required to be replaced again, thereby imposing a less burden to patients.
