The present invention aims to obtain a surface modification member which is bonded successfully to an implant material in a method for bonding a surface modification member and an implant material by using a slurry containing metal powders. The present invention is a biocompatible metallic porous plate to be bonded to the surface of in vivo implant material, wherein the area ratio A of open holes (a) present on the surface of the side facing the implant material is less than the area ratio B of open holes (b) present on the surface of the side facing a living body and the open holes (a) communicate through to the living body side. The biocompatible metallic porous plate is preferably produced by layered manufacturing.
