Abstract
An object of the present invention is to provide a radio wave absorber having excellent radio wave absorption against oblique incidence, particularly against oblique incidence of radio waves at around 79 GHz. The object can be achieved by a radio wave absorber having characteristic A: an absorption range with absorption performance of 15 dB or more within the frequency band of 75 to 85 GHz of 4 GHz or more in a TM polarization measurement at 45° incidence and/or characteristic B: an absorption range with absorption performance of 15 dB or more within the frequency band of 75 to 85 GHz of 4 GHz or more in a TE polarization measurement at 45° incidence.
