：。A connector that has a through hole in an insulating substrate made of polyimide resin or the like and holds a conductive rubber rod with carbon or metal powder arranged as a conductive filler on a rubber member is well known, and is mainly used for liquid crystal display devices and ICs that drive them. It is used as a face-down bonding connector. This type of connector, S, IC, etc.
Not only can a large number of protruding electrodes arranged in a matrix on two surfaces and the input terminals of the liquid crystal display device be bonded together, but also one of the elements can be bonded together.

の問題があった。1;・Although it has the advantage of being easy to replace, it requires a large pressing force due to the increased number of electrodes, and its volume resistivity is also relatively large, which has an adverse effect on the C-R time constant with the liquid crystal display device. However, there is a need for improvements in these areas, as they cannot be ignored and are unsuitable for circuits in which large amounts of current flow. As is well known, in order to perform high-density mounting, it is necessary to miniaturize the electrode diameter, and it is also necessary to reduce the resistance.For this reason, conventional connectors have a low conductive filler content. No method has been used to increase this to about 65%. However, such an increase in filler requires a large load as the rubber-like elasticity is lost, and the impact resilience is poor, so when replacing the element,
There were problems such as □ that the connector had to be replaced at the same time.

よってゴム状弾性が改善されろ。Therefore, as an improved conventional connector, a structure in which carbon or metal wires are oriented in the connection direction has been proposed. According to this conventional wire orientation structure, since the electrical resistance of the wire itself is low, the resistance can be lowered, and the rubber-like elasticity can be improved by reducing the amount of conductive filler y.
