Abstract
A pressure conductive sheet includes a connector body formed of a thin plate of insulation material, an elastic body deposited as one body with the connector body, pluralities of connection terminals provided with a given interval to pass through the elastic body and the connector body, and a ground plate constituting a matching circuit, the ground plate being buried by a given width in between the connector body and the elastic body. The ground plate is coupled to a ground terminal among the connection terminals and is separated from an outer circumference face of a signal terminal. The connector body, the elastic body, the connection terminals and the ground plate are combined with one another to substantially reduce an interference between signal terminals through the matching circuit formed based on capacitance of a gap between a ground face of the ground plate and the signal terminal, and to improve electrical characteristics.
