## Abstract

The present disclosure is directed to achieve greater space efficiency. A wiring module (A) includes a first transmission line (20), and a noise shielding member (40) that has a sheet shape and is arranged along the first transmission line (20). The noise shielding member (40) has a thickness of 100 μm to 600 μm. Since the noise shielding member (40) has a sheet shape, and thus the space for arranging the noise shielding member (40) can be made smaller, it is possible to achieve greater space efficiency. Since the noise shielding member (40) has a thickness of 100 μm to 600 μm, it is possible to obtain a high noise shielding effect.

## Claims

### Claim 1

A wiring module comprising:
a first transmission line and a second transmission line that extend along predetermined wiring paths;
a noise shielding member that extends along only the wiring path of the first transmission line; and
a sheet material,
wherein the first transmission line is constituted by a coaxial cable,
the noise shielding member has a sheet shape, and is separate from the first transmission line, and
the noise shielding member is layered on the sheet material, and then the first transmission line, the second transmission line, the sheet material, and the noise shielding member are fixed and integrated.

### Claim 2 (depends on 1)

The wiring module according to claim 1,
wherein the noise shielding member includes a magnetic material having such magnetic characteristics that an imaginary part of complex magnetic permeability between 1 GHz to 5 GHz is at least 5.

### Claim 3 (depends on 2)

The wiring module according to claim 2,
wherein the magnetic material has such magnetic characteristics that an imaginary part of complex magnetic permeability at a frequency of 1 GHz is at least 10.
