A metal wiring layer includes a plurality of hierarchical blocks each divided by a side that serves as a boundary. One of the hierarchical blocks is placed to extend along the outer periphery of the self hierarchical block, and includes: a shield ring wire formed by a single metal wire or by a plurality of metal wires; and a plurality of metal wires that are placed inside the shield ring wire and extend in a preferential direction determined in advance. The shield ring wire has a first section extending in the preferential direction and a second section extending in a non-preferential direction perpendicular to the preferential direction.
