Abstract
For the purpose of providing an electromagnetic wave absorber capable of holding excellent performance over a long period of time, the electromagnetic wave absorber includes: a dielectric layer B including a polymer film and having a first surface and a second surface; a resistive layer A formed on the first surface of the dielectric layer Band containing indium tin oxide as a main component; and an electrically conductive layer C formed on the second surface of the dielectric layer B and having a sheet resistance lower than that of the resistive layer A, wherein the indium tin oxide in the resistive layer A contains 20 to 40 wt. % of tin oxide based on the total weight of the indium tin oxide.
