The invention relates to a shielding module (1) for an annular transmitting coil/receiving coil (7) of a contactless energy transfer system (14). The shielding module (1) comprises a magnetic shield (2) having a magnetic conductivity or permeability µr ≥ 4, which has first recesses (B) in the region of a horizontal section (A), through which supports (3) made of a material with an electrical conductivity ≤ 10−4 S/m and a magnetic conductivity or permeability µr ≤ 2 extend. Furthermore, a transmitter/receiver (6, 6a, 6b) with such a shielding module (1) and a transmitting coil/receiving coil (7) is specified. Finally, the invention also relates to an energy transfer system (14) with such a transmitter (6, 6a) and a receiving coil (6b) installed in a motor vehicle (13).
