Specifically, a core wire is arranged on the central axis, and an insulator, a net-like shield wire, and a covering insulator that are concentric with the core wire are arranged in the radial direction from the axis. In a plug connector used to connect such a coaxial cable to an electronic device, the core wire is connected to a plug contact (see, for example, Patent Document 1), and the shield wire is connected to a ground member.

The plug connector used for such a coaxial cable includes a holding member made of an insulating material for holding the above-described plug contact, a metal shell member attached so as to cover the upper and lower bottom portions of the holding member, and the above-described ground member It is composed mainly of. On the other hand, the receptacle connector attached to the substrate side includes a receptacle contact, a holding member made of an insulating material that holds the receptacle contact, a metal shield member that is attached so as to cover the upper and lower bottom portions of the holding member, and a ground attached to the shell member Consists mainly of terminals. When the plug connector is engaged with the receptacle connector, the plug contact is connected to the receptacle contact and the electrical signal can be conducted, and the ground terminal is connected to the shell member and the ground signal can be conducted.
