PROBLEM TO BE SOLVED: To obtain an interference wave shielding structure for a radio wave receiving antenna for preventing an interference between a reception desired radio wave and an undesired electromagnetic interference wave by preventing the undesired electromagnetic interference wave from being incident to a radio wave receiving antenna, for example, such as a ground antenna for the radio wave reception of satellite communication. SOLUTION: This interference wave shielding structure 1 is provided with a rectangular hollow shielding structure 2 for enclosing the ground antenna 70 for satellite communication radio wave reception with the top end side left open to receive a satellite communication radio wave and preventing a direct wave of a ground wave from being incident to the antenna 70, and a radio wave absorber 3 attached to the inner surface of the rectangular hollow shielding structure 2 to absorb a diffracted wave of the ground wave.
