Abstract:
An object is to provide a λ/4 radio wave absorber that includes a support, a resistive film, a dielectric layer, and a reflective layer, and that has higher radio wave absorption performance. The object is achieved by a λ/4 radio wave absorber that includes a support, a resistive film, a dielectric layer, and a reflective layer, and that satisfies formula (1): −0.375x+1086.9
