1. A composite diamond body comprising:
- a diamond base material; and
at least one stable layer disposed in at least one ofa position on the diamond base material anda position in an inner region from a surface of the diamond base material to occupy at least a part of the diamond base material, whereinthe stable layer includes at least one layer which is an ion-implanted layer disposed in the inner region from the surface of the diamond base material to occupy at least a part of the diamond base material, wherein the ion-implanted layer includes separate portions located in respective multiple regions each having a diameter of less than 1 μ
m as seen in a direction perpendicular to the surface of the diamond base material.

Abstract
A composite diamond body includes a diamond base material and a stable layer disposed on the diamond base material. The stable layer may have a thickness of 0.001 μm or more and less than 10 μm, and may include a plurality of layers. A composite diamond tool includes the composite diamond body. There are thus provided highly wear-resistant composite diamond body and composite diamond tool that are even applicable to mirror-finish planarization of a workpiece which reacts with diamond to cause the diamond to wear.
