A first area, a ring shape second area surrounding the first area, and a third area surrounding the second area are defined on the surface of a support substrate. A first wiring layer is disposed above the support substrate. A wiring is formed in the third area, dummy patterns being formed in the second area, and conductive patterns are not formed in the first area. A functional element is disposed above the first wiring layer and in the first area.
