Connector device including conductive portion

A connector device, comprising:

• a pair of circuit boards including board transmission paths, the circuit boards being arranged to face each other;
• a pair of connectors to be individually mounted on the pair of circuit boards;
• a plurality of adapters including outer conductors, the adapters connecting the pair of connectors;
• an electrically nonconductive alignment portion for integrally and swingably holding the plurality of adapters;
• and
• an electrically conductive portion made of metal, the electrically conductive portion being attached to the alignment portion and making a plurality of the outer conductors conductive,
• the board transmission paths being arranged outside an inclusion region including the plurality of adapters on a virtual projection plane parallel to the circuit boards, and
• the electrically conductive portion being arranged only within the inclusion region on the virtual projection plane.
