Patent ID: 7470149

Claim:
A conductive-contact holder that accommodates at least a signal conductive-contact that is a conductive contact for performing input and output of a signal for a predetermined circuit configuration and a ground conductive-contact that is a conductive contact for supplying a ground potential to the predetermined circuit configuration, the conductive-contact holder comprising: a holder base that is formed of a conductive material, the holder base including a first opening for accommodating the signal conductive-contact; and a second opening for accommodating the ground conductive-contact while maintaining an electrical connection with the ground conductive-contact; and an insulating member that covers an inner surface of the first opening, wherein the ground conductive-contact includes a needle member which electrically contacts with the circuit configuration, and an elastic member which applies a pressing force to the needle member to project the needle member outward from the second opening while allowing the needle member to freely move along an axial line of the second opening, the elastic member being configured to contact with an inner surface of the second opening by being compressed when the circuit configuration is connected to the conductive-contact holder.
