Abstract A method of making an electrical current sensor having at least an electrical conducting portion of rectangular cross-section being surrounded, on three of its lateral faces, by a magnetic circuit portion which has end portions having planar surfaces situated substantially in a plane of a fourth lateral face of the conductor portion, a magnetic field detector being arranged opposite the fourth lateral face. The conductor portion is made by photo-lithography and etching in a layer of electrically conducting material applied on a first surface of a flat support member. The magnetic circuit portion is made by photo-lithography and etching in a layer of magnetically permeable material applied on the conductor portion on the first surface of the support member. The magnetic field detector is fixed to the support member deposited on a second surface of the support member.
