Abstract

A multipole connector includes a connector body that includes a first end surface and a second end surface; a plurality of contacts that are arranged and led to the first end surface of the connector body; and a ground plate. The multipole connector is connected to a cable in which ground meshes forming external conductors that are to be grounds and core wires that are to be signal lines are insulated from each other by an inner jacket and the outer side is sheathed with an outer jacket. The signal lines are connected to signal line contacts in the contacts, respectively, the ground meshes are connected together on the ground plate, and the ground plate is connected to at least one of the ground contacts of the contacts.
