A method of fabricating a heatsink including a substrate of a sintered compact containing Cu and W, and a thin diamond film layer formed on the surface of the substrate with good adherence, involves immersing the substrate in acid to reduce the Cu content of a surface region thereof and to roughen exposed W at that surface region, and then forming the thin diamond film layer on that surface region by vapor synthesis. Alternatively, a thin diamond film layer is formed on a surface of a porous body substrate, and then a hole in the porous body substrate is filled with Cu.
