ABSTRACT OF THE DISCLOSURE The printed inductance comprises at least a first con- ductive spiral which is supported by one of the faces of a flexible insulating supporting-plate. The supporting-plate is folded back through 180° along an axis passing through the geometric origin of the spiral which coincides with the inter- nal connecting terminal of the conductive spiral, so as to pro- duce a magnetic field coplanar to the folded supporting-plate. A second conductive sprial may be supported by the other face of the supporting-plate. The first and second spirals are iden- tical and symmetrical with respect to the fold axis. A hole having metallized walls connects the internal terminals of the spirals therebetween. A flat magnetic element and/or an insu- lating insert may be sandwiched by the inside facing half-faces of the supporting-plate. The printed inductance may be used in a magnetic transcription device.
