A microwave absorber in a pointed shape, including a phenol resin foam containing a dielectric loss material, is prepared by setting an incombustible sheet container of a same shape in a mold in a pointed shape, pouring the phenol resin to which the dielectric loss material is blended, and foaming and curing. As a result, a semi-incombustible or incombustible microwave absorber of high strength possessing a high microwave absorption capacity in a wideband is obtained.
