COAXIAL CABLE CONNECTION MODULE, MULTIPOLAR CONNECTOR FOR COAXIAL CABLE, AND MULTIPOLAR COMPOSITE CONNECTOR

PROBLEM TO BE SOLVED: To increase the number of connectable cables in a multipolar connector while suppressing increase in size of the multipolar connector without deteriorating the high-frequency transmission characteristics of a coaxial cable.SOLUTION: A module 10 has: a main body 14 having first and second surfaces 20 and 22 opposite to each other; a first signal terminal 16 and a first ground terminal 18 provided on the first surface 20; and a second signal terminal and a second ground terminal provided on the second surface 22. A first signal contact surface 38a of the first signal terminal 16 and a first ground contact surface 44a of the first ground terminal 18 are arranged in parallel to each other on the first surface 20 at a preliminarily-defined pitch. A second signal contact surface of the second signal terminal and a second ground contact surface of the second ground terminal are arranged in parallel to each other on the second surface 22 at the pitch. The second ground contact surface is arranged on an opposite side to the first signal contact surface 38a. The second signal contact surface is arranged on an opposite side to the first ground contact surface 44a.
