PROBLEM TO BE SOLVED: To provide a radio wave absorbing panel for a glass curtain wall having satisfactory radio wave absorbing characteristics to the radio waves over a wide frequency range in various incident angles. SOLUTION: The glass, an air layer, a radio wave absorber and a reflector are arranged in this order. In this case, as the structure of the radio wave absorber, a ferrite stick 3 having width A of 16 to 23 mm, thickness B of 15 to 22 mm and satisfying condition of A>=B is used, the ferrite sticks are arranged with the gap rate of 70 to 85% in the electric field direction of coming radio waves and continuously in a magnetic field direction and the ferrite sticks 3 are fixed in grooves on the bottom of a box-shaped metal case 1.
