PURPOSE: To provide a light radio-wave absorbing panel in structure suitable even for a complex surface configuration, by inserting tube-shaped ferrite bodies between reinforcing bars at least partly.

CONSTITUTION: A radio-wave absorbing panel has a plane part with a length (f) of 800mm and a circumference part with a length (e) of 1600mm, and a length (g) is 150mm and a height (h) is 200mm. At a plane part, plane ferrite plates 1 are arranged continuously in a magnetic field direction, while the ferrite plates 1 are arranged intermittently with a gap ratio of 70% in an electric field direction. At a circumference part has tube-shaped ferrite bodies 3 each with an outer diameter of 25mm, inner diameter of 6.1mm, and length of 40mm are inserted between reinforcing bars 2 in the electric field direction. Consequently, a lightweight radio-wave absorbing panel suitable even for a complex surface structure can be formed, and stable radio-wave absorbing characteristics are ensured irrespective of changes in angles of incidence of the radio wave.
