An electromagnetic wave absorption material comprises: fibrous carbon nanostructures; and an insulating material, wherein a content C of the fibrous carbon nanostructures when a content of the insulating material is 100 parts by mass is 5 parts by mass or more and 15 parts by mass or less, or, in the case where the fibrous carbon nanostructures are fibrous carbon nanostructures that exhibit a convex upward shape in a t-plot obtained from an adsorption isotherm, the content C is 0.3 parts by mass or more and 0.8 parts by mass or less, and the electromagnetic wave absorption material absorbs an electromagnetic wave in a frequency domain of more than 20 GHz.
