The substrate holder includes a first holding member and a second holding member clamping the substrate between the first holding member and it and having a contact which contacts a peripheral part of the substrate and supplies an electric current to the substrate. The second holding member includes an opening defining a region where an electric field is formed and, at a position farther from the substrate than the opening, a shielding part protruding closer to an inner side than the opening and shielding the peripheral part of a surface of the substrate. The shielding part has a frame shape having a predetermined shielding width in the peripheral part of the substrate, and has, at a corner part thereof, a discontinuous part having a smaller shielding width than surroundings."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Substrate holder and plating device","description":"According to an embodiment, a substrate holder holds a rectangular substrate and performs electrolytic plating on the substrate.
