Abstract
The radio wave absorber includes one or more kinds of particles selected from the group consisting of magnetic particles and dielectric particles, and a binder, and a ten-point average roughness Rz of at least one of a pair of main surfaces of the radio wave absorber facing each other is 25 μm or more and Y μm or less. The Y is a value calculated by Y=λ×1000/10, where λ mm is a wavelength of a radio wave transmitted from the radio wave transmitter.

An article comprising:
- a radio wave transmitter;
- and
- a radio wave absorber,
- wherein the radio wave absorber contains one or more kinds of particles selected from the group consisting of magnetic particles and dielectric particles, and a binder, and
- a ten-point average roughness Rz of at least one of a pair of main surfaces of the radio wave absorber facing each other is 25 μm or more and Y μm or less,
