PURPOSE:To obtain an electrode needle polishing disk which is suitable for mass production, by forming with a stamper which is produced through a master board and mother board formed by the plating method from a blank board having grooves formed by an energy beam in the photoresist layer. CONSTITUTION:A blank board with grooves 35 is produced in such a way that a photoresist 33 is formed on the surface of a prescribed base, such as a glass plate 31 on which a metallic reflecting layer 32 is installed, and the photoresist layer 33 is exposed to an energy beam 34, such as laser beam, etc., and developed, and then, an after-baking is performed on the base. Then, a master board 36, mother board 37, and stamper 38 are successively produced by the plating method with the blank board. An electrode needle polishing disk having grooves 40 to be used for polishing the pointed end of electrode needles to a prescribed shape is formed with the stamper 38. |
