Abstract
The present invention belongs to a technical field for manufacturing a three-dimensional structure for an electronic device such as a radio wave shielding member through extension working of a metal plate having cuts. In conventional three-dimensional working of a metal plate, there is a problem in that a non-extension portion is wrinkled depending on extension of a cut. In the present invention, a connecting portion (3) extended in a second direction (D2) is provided at an equal pitch (p) in a first direction (D1) through an opening (4) having a rectangular cross-section in an intermediate portion (PB) between a cut forming portion (PC) having cuts (2) provided like a zigzag in the first direction (D1) and a non-extension portion (PA) having no cut in a metal plate (1). Consequently, even if the cut forming portion (PC) is extended, the connecting portion (3) is simply squashed and contracted and a boundary line (BL) portion is not deformed.
