Semiconductor device

A semiconductor device, comprising:

• a substrate that includes a substrate main surface facing a thickness direction;
• a semiconductor element that includes an element main surface facing the substrate main surface, a first element electrode formed on the element main surface, and a second element electrode formed on the element main surface;
• a first through-electrode that extends through the substrate and includes a first electrode upper surface facing the same direction as the substrate main surface;
• a second through-electrode that extends through the substrate and includes a second electrode upper surface facing the same direction as the substrate main surface;
• a first main surface wiring line that contacts the substrate main surface and the first electrode upper surface and includes a first wiring line upper surface facing the same direction as the substrate main surface;
• a second main surface wiring line that contacts the second electrode upper surface and includes a second wiring line upper surface facing the same direction as the substrate main surface;
• a first wiring line electrode formed on the first wiring line upper surface;
• and
• a second wiring line electrode formed on the second wiring line upper surface.
