Abstract
A laminated body includes a first insulating sheet having first internal conductors disposed thereon, a second insulating sheet having second internal conductors are given, and a protective sheet, wherein the internal conductors define inductors. The first insulating sheet, the second insulating sheet and the protective sheet are stacked on top of each other and laminated to define the laminated body. When a distance between the end surfaces in a length direction of the laminated body and the inductors located adjacent the end surfaces is less than a fixed value, the internal conductors defining the inductors on the side of the end surfaces are arranged in a zig zag pattern which extends toward inner inductors.
Claims20
An inductor array comprising:
- a laminated body including insulating material layers and substantially linear internal conductors which are stacked on each other;
- a plurality of pairs of external input and output electrodes provided on a surface of the laminated body;
- and
- a plurality of inductors arranged such that both ends of each of the internal conductors are connected to the external input and output electrodes;
- wherein the shape of a first group of the internal conductors which are located adjacent to end surfaces of the laminated body is different from the shape of a second group of the internal conductors disposed inside of the first group of the inductors which are located adjacent to the end surfaces of the laminated body so that the inductance of each of the inductors is substantially equal.
