Electrical heating wire comprising a central core (1 ) defining a longitudinal development (Y), a first electrical resistive wire (2), wound around said central core (1 ) so as to define a first coil and an insulating coating sheath (3,5) of the electrical resistive wire (2); said electrical resistive wire (2) having a flattened section comprising a first dimension (D1 ) and a second dimension (S1 ) that is smaller than the first dimension, respectively according to axes that are perpendicular to each other, and in that the second dimension is radially arranged with respect to the development of the core, wherein the section of the resistive wire has a side (2a, 2b) intended to come into contact with the insulating sheath (3, 5) with rounded edges (20). |
