摘要： According to an embodiment, high-frequency signal transmission device includes a connector and a wiring board with two cable ends. The connector includes contact terminals with signal contact terminals and ground contact terminals. In a wiring board, signal contact pads, ground contact pads and one or more ground layers are formed on at least one of the cable ends. The ground contact terminal includes an arm portion bent so as to locally abut against the ground contact pad at a contact portion. The contact portion of the arm portion is positioned so as to (i) at least partially abut against a surface of a covering portion of the ground contact pad covering the first penetrating electrode directly above the first penetrating electrode, or (ii) abut against the ground contact pad near an outer periphery of the covering portion, when the wiring board is electrically connected to the connector.

摘要： High-frequency signal transmission cable includes: a dielectric layer; and first and second wiring layers arranged to sandwich the dielectric layer. The first wiring layer includes at least M (M indicating a natural number of 2 or more) differential transmission lines. The first wiring layer further includes a group of first ground lines including at least 2×M first ground lines. The second wiring layer includes a group of second ground lines including at least M second ground lines. The group of first ground lines are allocated to the M differential transmission lines in accordance with a condition of at least two first ground lines per one differential transmission line in non-overlap manner, and the group of second ground lines are allocated to the M differential transmission lines in accordance with a condition of at least one second ground line per one differential transmission line in non-overlap manner. Each of the differential transmission lines is interposed between the at least two first ground lines and is opposed to the at least one second ground line.

摘要： Connector to which a high-frequency signal transmission cable is electrically coupled includes: an insulator; a group of contact terminals including at least M unit arrays arranged in a width direction of the insulator, each unit array including one or more signal contact terminals and one or more ground contact terminals. The insulator includes an insulator body and at least M attachment members which are attached to the insulator body and arranged in the width direction of the insulator. The respective unit arrays included in the at least M unit arrays are respectively supported by the respective attachment members included in the at least M attachment members.
