    摘要: An electrically conductive member constituted by at least one member of the group consisting of carbon black, graphite and carbon fiber, a powdered or granulated material of an inorganic hollow body and inorganic reinforcing fiber are bonded to one another by an inorganic adhesive agent to thereby form an electric wave absorber. The electric wave absorber exhibits excellent electric wave absorbing power because of both the electrically conductive member and the powdered or granulated material of the inorganic hollow body which are contained in the electric wave absorber. The electric wave absorber has excellent mechanical strength because of the inorganic reinforcing fiber which is contained in the electric wave absorber. The electric wave absorber exhibits excellent nonflammable characteristic because of both the powdered or granulated material of the inorganic hollow body and the inorganic reinforcing fiber which are contained in the electric wave absorber. Preferably, the electric wave absorber is provided with a nonflammable layer which is integrally bonded to at least one portion thereof and which is constituted by at least one member of the group consisting of a nonflammable sheet made from a slurry containing sepiolite as a main component, and an inorganic coating agent layer.
