摘要

An object of the present invention is to make the potential distribution in a lattice uniform, prevent local corrosion, and extend the product life. SOLUTION: A frame bone 2 having a rectangular shape, an ear portion 21 formed upward from an upper side 2a of the frame bone 2, and one or a plurality of main longitudinal bones 3X extending below the ear portion 21 in the frame bone 2. And a plurality of slanted bones 4 that branch at least partially from the main longitudinal bone 3X, go to both sides about the main longitudinal bone 3X, and extend obliquely from the upper side 2a to the lower side 2b The plurality of oblique bones 4 are arranged at intervals in the extending direction of the main longitudinal bone 3X, and the shape of the plurality of space portions defined with the main longitudinal bone 3X as a part of the side is at least partly In FIG.
