Abstract
The invention relates to a current sensor or transducer (10) for measuring the current flowing through an electric conductor (11), comprising a magnetoresistive tape (12) surrounding the conductor and whose ends (13, 14) are to be connected to a device for measuring said current, characterized in that the tape (12) is shaped like a tube with an axis centred on the conductor and in that it is formed with a multilayer, metallic, magnetic structure, whose layers constitute the same number of stacked elementary tubes concentric to said axis.
