PROBLEM TO BE SOLVED: To improve absorption characteristics of a radiowave absorber for a radiowave from an oblique direction. SOLUTION: The radiowave absorber includes a first film made of a conductor, a second conductor made of a resistor, and a plurality of conductive patches made of conductors and arranged in a matrix between the first film and second film, wherein mutually adjacent conductive patches are different in area. A conductive patch having large area between the mutually adjacent conductive patches has the area which is 102 to 120% of the area of the conductive patch having the small area.
