• We considered an elastic contact problem of a half-space indented by a truncated conical stamp, and obtained its rigorous solution. We showed the relation among the resultant load, the indented depth and the configuration of the stamp, and the distributions of the surface displacements and the contact pressures. The surface normal displacement is always larger than the result for a cylindrical stamp, and the difference becomes larger as the slope of the side plane of the stamp, k, tends to be small. The contact pressure has a logarithmic singularity at the corner (r=a) and becomes zero at the contact boundary (r=b). The pressure in r<a is smaller than that for a cylindrical stamp.
