It is to provide an implant with shock-absorbing property that is able to
be strongly secured in a living body as well as a manufacturing method of
such implant.The implant comprising: a substrate; a first film on the
substrate, which is comprised of a polymer and has a functional group
that enables adsorption of calcium ions; and a second film formed on the
first film and being comprised of calcium phosphate. The manufacturing
method of the implant comprising: forming said first film on a substrate;
and subsequently, dipping the substrate in a calcium ion solution and in
a phosphate ion solution alternately as to form the second film.
