ABSTRACT:
A semiconductor device substrate includes a substrate body having a wiring layer. A base is formed by a material that is different from a material of the substrate body. The base supports the substrate body, and has an opening forming portion where a semiconductor element is mounted. A reinforcing member is larger than the opening forming portion, provided in the substrate body at a portion corresponding to the opening forming portion, and reinforces the substrate body at the portion corresponding to the opening forming portion.
