摘要
In an X-ray topography image for a crystal growth main surface (20m) of a single-crystal diamond (20), a group of crystal defect points (20dp) are gathered, each of the crystal defect points (20dp) being a tip point of a crystal defect line (20dq) reaching the crystal growth main surface (20m), the crystal defect line (20dq) representing a line in which a crystal defect (20d) exists. Further, in the single-crystal diamond (20), a plurality of crystal defect line-like gathered regions (20r) exist in parallel. In the plurality of crystal defect line-like gathered regions (20r), groups of crystal defect points (20dp) are gathered to extend in the form of lines in a direction angled by not more than 30° relative to one arbitrarily specified direction. Accordingly, a single-crystal diamond is provided which is used suitably for a cutting tool, a polishing tool, an optical component, an electronic component, a semiconductor material, and the like.
