The manufacturing method for components of the inductive type, in particular inductance coils, transformers or antennae, consists in making by micro-machining simultaneously on a first substrate made of magnetic material a plurality of first parts ( 1 ) connected to each other by connecting elements ( 2 ) or a connecting support, inserting on the arms ( 8 a , 8 b , 8 c) of these first parts ( 1 ) a printed multi-layered plate ( 4, 5 ) having openings for the arms and metal windings ending in at least two contact pads ( 7 a , 7 b), in placing and securing a second substrate made of magnetic material on the first substrate and the plate, said second substrate having undergone micro-machining to obtain second parts ( 13 ) complementary to the first parts. These second parts are connected to each other by connecting elements or a connecting support. Then, the components are separated and, in a particular implementation, the contact pads arranged on tongues ( 16, 18 ) of said plate are folded against a base ( 9 ) of the core or of the magnetic circuit to form a surface mounting device.
