Claim Text:
1. A coaxial-type electric connector having: an insulative housing to which a terminal part of a cable-shaped signal transmission medium is coupled, an external conductor shell consisting of an approximately hollow cylindrical member attached so as to cover an outer surface of the insulative housing, and an internal conductor contact disposed in a radial-direction inner region of the external conductor shell; the coaxial-type electric connector configured so that: a wire connection part of the terminal part of the cable-shaped signal transmission medium and the internal conductor contact is disposed in the radial-direction inner region of the external conductor shell, a shell cover portion that opens/closes an annular opening possessed by the external conductor shell is openably/closably coupled to the annular opening, an insulative pressing plate integrally opened/closed with the shell cover portion is provided at the insulative housing, and, when the shell cover portion is closed so as to cover the annular opening of the external conductor shell and the insulative pressing plate is deformed so as to form a bent portion, pressing force of the insulative pressing plate causes a tongue-shaped portion of the internal conductor contact to contact the cable-shaped signal transmission medium with pressure and form the wire connection part; wherein a void portion formed by an inner wall of a groove dented to form a step shape is provided in part of a surface of the insulative pressing plate and at a position facing the wire connection part of the terminal part of the cable-shaped signal transmission medium and the internal conductor contact; the void portion is disposed in the radial-direction inner region of the external conductor shell and is formed so that a bore size (W
