In a radio wave absorber for absorbing electromagnetic waves in a frequency band of 400 to 1000 MHz or less, a radio wave absorber having both weight reduction and thinning, a radio wave absorption panel structure using the same, and wireless communication improvement Provide a system. A pattern layer having a conductor element, a loss layer including at least one of a magnetic loss material and a dielectric loss material, and a dielectric layer including a dielectric material. 3 and at least one layer is laminated in this order, and the dielectric material has a density of less than 1.0 g / cm 3 .
