  • Patent number: 11584641
    Abstract: The purpose of the present invention is to provide a method for manufacturing a three-dimensionally structured member which can be made by a simpler process. The method for manufacturing a three-dimensionally structured member includes shaping a flat plate-shaped base member to produce a three-dimensionally structured member having a plurality of sections that are different from one another in thickness. The manufacturing method comprises: a mask formation step for forming a mask over the whole of at least one main surface of the base member; a mask removal step for removing a part of the mask; and an etching step for etching an exposed part of the base member wherein a combination of the mask removal step and the etching step is performed on the mask and the base member that correspond to each of the plurality of sections of the three-dimensionally structured member, in the order from thinnest to the thickest of thicknesses of the three-dimensionally structured members.
