Abstract
A wave absorber comprising first foamed particles comprising foamed particles of a thermoplastic organic polymer and a conductive layer formed on the surface thereof, and second foamed particles comprising foamed particles of a thermoplastic organic polymer, the first foamed particles and the second foamed particles being melt-adhered to each other, and a method for producing same. The wave absorber of the present invention is superior in a long-term shape retention, and shows superior wave absorption performance, thereby rendering itself suitable for use in an anechoic chamber.
