<p>A composite shape electroforming master, its electroforming master and a method for manufacturing the same are disclosed, in which the electroforming member has various sections. The electroforming master is made by the steps of forming an electrode base including an insulating portion which is not electrically connected and a conducting portion having the same shape as that of the electroforming member, forming metal layers in the conducting portion by performing an electroforming process in the surface of the electrode base and exposing portions in the insulating portion, sequentially increasing the height of the metal layers and the height of the exposing portions, removing the exposing portions from the electrode base to form a space portion when the metal layers and the exposing portions reach a desired height, forming a pin portion by filling an insulating material in the space portion, and removing the metal layers remaining on the electrode base from the electrode base after the pin portion is hardened. The composite shape electroforming member can have various shapes by gradually varying the size and the position of the exposing portions when the exposing portions are formed using a film. That is, the pin portion of the insulating material protruded upward of the surface of the electrode base is formed with a varied section in a vertical direction by gradually varying the size and the position of the exposing portions. As a result, the electroforming member having various sections varied vertically can be obtained.</p> |
