The current transducer is of the type comprising a Rogowski coil extending around a first conducting element in which a current to be detected flows. The first conducting element is provided at one end with a first terminal connector. A second conducting element is mounted on the first one so as to cover and preferably embed the external periphery of the coil. The second conducting element is electrically connected to the first conducting element at the end thereof which is opposite to the one end provided with the first terminal connector. A second terminal connector is provided on the second conducting element on the same side of the plane of the coil as the first terminal connector. This arrangement forces the current flowing between the first and second terminal connectors via the first and second conducting elements to flow around the periphery of the coil and thus to shield the coil.
