Inlay for electronic document, method for producing an electronic document comprising such an inlay, and electronic document obtained

A method for producing an electronic document, comprising:

• making available a body of the electronic document, the body including at least:
• an inlay having at least one substrate and at least one first zigzag portion formed of a metal wire embedded in an upper face of the at least one substrate, the at least one first zigzag portion including, alternately, rectilinear segments and bends, a bend connecting two successive rectilinear segments, at least one of the rectilinear segments of the at least one first zigzag portion being disposed, at least in part, in a zone of the upper face of the substrate configured to form a spotface of a cavity of the electronic document, and the inlay including a connection wire configured to join together at least the rectilinear segments of the at least one first zigzag portion;
• and
• at least one upper layer which covers the upper face of the substrate of the inlay, and a lower layer, the substrate of the inlay being disposed between the at least one upper layer and the lower layer;
• and
• forming the cavity in the body including at least machining at least the at least one upper layer of the body by way of a machine tool, the machine tool having a cutting direction forming an angle of between 80° and 100° with respect to a rectilinear segment of the at least one first zigzag portion.

An electronic document comprising:

• a body including:
• a cavity hollowed out in a part of a thickness of the body, the cavity comprising a deep central part and a peripheral part, formed of a spotface, less deep than the deep central part and surrounding the deep central part, and
• an inlay comprising at least one substrate and at least one first zigzag portion formed of a metal wire embedded in an upper face of the substrate, the at least one first zigzag portion comprising, alternately, rectilinear segments and bends, a bend connecting two successive rectilinear segments, the at least one first zigzag portion forming a connection pad, exposed on the spotface, and the inlay comprising at least one connection wire joining together the rectilinear segments of the at least one first zigzag portion;
• and
• a module inserted into the cavity and having at least one connection terminal being in electrical contact with the at least one first zigzag portion of the inlay.
