Abstract
A radio wave absorbing panel is made up of a first insulating substrate and a second insulating substrate disposed in parallel a predetermined distance apart and a middle insulating substrate disposed between and parallel with the first and second substrates. The first and second substrates each have a conducting film coated over the entire surface of one side. On one side of the middle insulating substrate are coated multiple conducting films disposed in the form of stripes or a matrix. The width of each of the conducting films disposed in the form of stripes or a matrix is equal to or between 0.1 cm to 50 cm. By this means a thin radio wave absorbing panel having excellent radio wave absorption and transparency to light can be obtained.
