To provide a biological implantation member-coating material capable of preventing adverse influence on a living body due to implantation of the biological implantation member inside the living body by obtaining strong adhesion with viable tissues since cells easily intrude from living body subcutaneous tissues, are taken, and are organized into tissues.

The biological implantation member-coating material is provided with a communicable porous three-dimensional net-like structure part formed of a thermoplastic resin or a thermosetting resin, whose average pore size is 100 to 1,000 μm and apparent density is 0.01 to 0.5 g/cm3.
