PROBLEM TO BE SOLVED: To provide a thin radio wave absorber whose radio wave absorption quality depends upon a wavelength, and which is usable in a package required to be compact. SOLUTION: The radio wave absorber comprises a patch antenna 1 etc., formed on a surface of a thin film substrate 50 made of a dielectric, and is made thin while the radio wave absorption quantity is made dependent on a wavelength by radio wave reception characteristics of the antenna 1.
