[PROBLEMS] To have a high radio wave absorptivity regardless of the incident angle of radio waves, excellent handleability, office, store, etc. The present invention provides an electromagnetic wave absorber that can be manufactured at a manufacturing cost that can be generally used as a distribution warehouse, public building, general house, and condominium general building material. An electromagnetic wave absorber formed by laminating at least one resistive film layer 2, a spacer layer 3, a layer 4 containing an electrical loss material, and a reflection layer 5, and containing the electrical loss material The wave absorber has a layer thickness of d / 8 or more with respect to the total thickness d of the wave absorber.
