Summary:PURPOSE: A manufacturing method for a porous electroforming mold is provided to prevent the blockage due to foreign materials and improve suction force by forming a bell-shaped expansion hole on a second surface layer. CONSTITUTION: A manufacturing method for a porous electroforming mold comprises the steps of: manufacturing a model with a conductive film(10) on a surface, performing a electroforming process on the conductive film to form a first metal surface layer(14), boring a plurality of holes(22) in the model with the first metal surface layer formed, and supplying gas to the holes and forming a second metal surface layer on the first metal surface layer.
