An integrated circuit card with two connection modes. The integrated circuit card includes a card body in which there is embedded a link circuit for linking a contactless coupling element (,) to a module having an integrated circuit (,) connected to conductive areas carried by a support film (,). The link circuit extends in register with conductive areas (,) dedicated to making a contactless link and is connected to said conductive areas by an electrically conductive material (,) filling blind holes (,). The blind holes have sections that increase from a bottom of each hole towards an opening thereof over at least a portion of their height.
