- conductive layers 65 and 67 are connected via insulating layer 68 therebetween. It is assumed that the conductive layer 65 is grounded and the conductive layer 67 is connected to the power source. In this case, configuration 70 functions as capacitor C.
- the parasitic capacitance can be reduced and the guard layer functions as a shield wiring.
- the substrate is a semiconductor substrate such as a silicon substrate or a conductive substrate as shown in the embodiment mode
- the substrate is held at a potential different from that of the conductive layer 65 or the conductive layer 67.
- the same potential as that of at least one of the conductive layer 65 and the conductive layer 67 may be maintained.
- the present invention is not limited to this, and may be a rectangle or a polygon.
- the force described above is an example in which a silicon substrate is used as the substrate.
- the present invention is not limited to this, and a glass substrate may be an insulating substrate such as a sapphire substrate.
- the through substrate and the interposer according to the present invention can be advantageously used as a substrate having the same function as that of the coaxial cable.
