2. Description of the Related Art Conventionally, a coaxial cable has been generally used as a line for transmitting a high-frequency signal, but recently, with the downsizing of electronic equipment, the high-frequency transmission line is also required to be small and thin. Parallel strip line cables that can be made thinner and thinner have been used.

FIG. 12 is a perspective view of a connection terminal 110 of a conventional parallel stripline cable. As shown in FIG. 12, the parallel stripline cable includes a dielectric 112b having a ground conductor 111b formed on the lower surface and a strip conductor 113 formed at the center in the width direction of the upper surface.
It is composed of a dielectric 112a having a ground conductor 111a formed on its upper surface, and a lower surface of the dielectric 112a and an upper surface of the dielectric 112b are joined together. Here, in order to make the parallel stripline cable flexible, the dielectric 11
2a and 112b are made of a flexible dielectric material.

As shown in FIG. 13, the connector 150 includes a substantially cubic insulating case 102 having a connection recess 103 formed therein. An elastic terminal 108 is provided in the connection recess 103 so that the tip of the connection terminal 110 contacts the strip conductor 113 when the connection terminal 110 is inserted into the connection recess 103, and the connection terminal 110 is inserted into the connection recess 103. At times, the elastic terminal 109 is provided so that its tip portion comes into contact with the ground conductor 111b. In addition, the elastic terminal 10

However, in the connection terminal 110 of the parallel strip line cable of the conventional example, since the dielectric materials 112a and 112b are made of a flexible dielectric material, the connection terminal 110 and the connector 150 are used. When the terminal is repeatedly attached and detached, or for a long time, the elastic terminal 10
8 and the strip conductor 113 are in contact with each other, there is a problem that the strip conductor 113 in a portion in contact with the elastic terminal 108 is gradually depressed into the inside of the dielectric body 112b and the contact resistance is gradually increased. Further, in the connection terminal 110 of the conventional parallel stripline cable, the strip conductor 113 and the ground conductor 111 used as connection conductors are used.
Since b is not located on the same plane, the circuit board 120
There is a problem in that it is difficult to directly solder and bond the electrodes formed on the one surface.

An object of the present invention is to solve the above-mentioned problems and to reduce the contact resistance in the case where the connector is repeatedly attached and detached or when the connector is continuously connected for a long time as compared with the conventional example. An object of the present invention is to provide a connecting terminal for a parallel stripline cable which can be prevented from increasing and can be connected by soldering.
