An electromagnetic wave absorptive film for absorbing electromagnetic waves by means of destructive interference is disclosed to include a compound layer, which has single-layer and/or double-layer wave-absorbing and/or wave reflecting grains embedded therein and a thickness equal to 1/4n times of the wavelength of the electromagnetic wave to be absorbed, and a reflective layer, which is covered on one side of the compound layer and has a refractive index greater than the compound layer.
