A method of producing a needle-like diamond structure including the steps of forming a layer of anodized alumina on a diamond substrate, the anodized alumina having a plurality of through holes; vapor-depositing a substance resistant to plasma etching by a vacuum vapor-depositing method to form dots on said diamond substrate, wherein the layer of anodized alumina acts as a mask for the vapor deposition; removing the anodized alumina; and performing a plasma etching treatment while using the dots as a mask, thereby forming regularly-arranged, needle-like diamond columns.
