An inspection head of an eddy current non-destructive testing sensor with separate transmitting and receiving functions includes a support whereon is arranged at least one transmitting/receiving element. Each element includes a circuit transmitting a local electromagnetic field, by circulating a predefined alternating current in the circuit, and an electromagnetic receiver sensitive to the locally transmitted electromagnetic field. The transmitting circuit is a portion of conductive sheet extending over a layer of the support layer in a predefined main direction of flow of the alternating current. The electromagnetic receiver is disposed facing the transmitting circuit relative to an axis normal to the layer of the support on which the portion of sheet extends to have an electromagnetic detection axis orthogonal to this normal axis and orthogonal to the predefined main direction of flow of the alternating current in the portion of conductive sheet. |
