Abstract
A radio wave absorber () includes a resistive layer (), an electrical conductor (), and a dielectric layer (). The resistive layer () includes indium tin oxide as a main component. The electrical conductor () reflects a radio wave. The dielectric layer () is disposed between the resistive layer () and the electrical conductor () in the thickness direction of the resistive layer (). The dielectric layer () is formed of a polymer. The content of tin oxide in the indium tin oxide included in the resistive layer () is more than 0 weight % and less than 20 weight %. The number of hydrogen atoms included in the resistive layer () is 5% or more of the total number of indium atoms, tin atoms, oxygen atoms, and hydrogen atoms included in the resistive layer ().
