Abstract:
Parasitic capacitance between upper and lower adjacent wirings of an inductor using a multilayer wiring layer in an insulating film formed on a base substrate is reduced. An inductor is characterized by having one go-around of go-around wiring (A-B or B-C) formed in each of at least two of adjacent wiring layers of a plurality of wiring layers 18 placed in an insulating film on a base substrate, and in that one end (B) of the one go-around of go-around wiring (A-B and B-C) formed in each of the at least two of wiring layers is connected to each other at a via and the one go-around of go-around wiring (A-B and B-C) formed in each of the at least two of wiring layers is placed at substantially the same position in a surface of the base substrate when viewed from an upper side of the base substrate.
