Beschreibung
Zusammenfassung:	The invention relates to an air inlet duct (11) for a turbojet nacelle, comprising an upstream annular lip (13) and a downstream outer annular structure (14Ex). The invention is characterised in that the upstream annular lip (13) and the downstream outer annular structure (14Ex) are formed as a one-piece part (15) made from composite material and in that the upstream lip (13) is covered with a metal layer (16) formed, in particular, by electrodeposition or plastic forming. The invention also relates to a turbofan engine having an air inlet duct (11) thus formed, and to a method for producing one such air inlet duct (11).
