Abstract
A wiring board (package) has a structure in which multiple wiring layers are stacked one on top of another with insulating layers each interposed between corresponding two of the wiring layers, and the wiring layers are connected to one another through vias formed in each of the insulating layers. In a peripheral region of the package, reinforcing patterns are provided on the same surfaces where the corresponding wiring layers are provided, respectively. Each of the reinforcing patterns is formed of a conductive layer formed on the same surface where the corresponding one of the wiring layers is provided, and is provided in an intermittent ring-like shape when viewed in a planar view.
