Abstract
A radio wave absorbing member 1a includes a radio wave absorber 10 and a support 20 having a sheet shape. The radio wave absorber 10 includes a resistive layer 12, a reflective layer 14, and a dielectric layer 13. The reflective layer 14 reflects a radio wave. The dielectric layer 13 is disposed between the resistive layer 12 and the reflective layer 14 in the thickness direction of the reflective layer 14. The support 20 supports the radio wave absorber 10. The support 20 includes a matrix resin 20m and a flame retardant 20p.
