An electromagnetic wave absorber that is lightweight, excellent in workability, and has high electromagnetic wave absorption performance in a low frequency band, and a method for producing the electromagnetic wave absorber. An electromagnetic wave absorbing sheet (1) in a frequency band of 4.9 to 7.05 GHz, comprising a DCF (2), a dielectric layer (3), and an electromagnetic wave reflection layer (4), comprising: a dielectric layer (3); The thickness D of the first resin layer 5 between the DCF 2 and joining the opposing surfaces of the dielectric layer 3 and the DCF 2 to each other is configured to be 5 μm to 300 μm.
