め、低コストで高い生産性を有する。The anisotropically conductive elastomer sheet obtained by the present invention and the method for producing the same have many advantages in terms of production and properties compared to conventional ones. In other words, the conventional manufacturing method for anisotropically conductive elastomer sheets has problems with inherent variations in the material and difficulty in controlling the posture of the conductor, which has been a major bottleneck in producing large quantities of product pipes with uniform performance. . However, according to the present invention, the conductive fibers that are the warp are fixed to the insulating fibers that are the weft,
Moreover, since mutual insulation between the conductive fibers is guaranteed, the productivity of the sheet can be significantly increased. Furthermore, the anisotropically conductive nidistomer sheet obtained by the present invention can be used in a manner where it is subjected to repeated compression many times.
Extremely advantageous in terms of durability. That is, when the elastomer sheet is subjected to repeated compression tubes many times, it is believed that the deterioration in the reliability of electrical contact is caused by at least two factors. One is a decrease in the elasticity of the elastane (-), and the other is deformation of the conductor (especially conductive fibers). These two factors cause the contact pressure between the terminal of the circuit element pressed against the elastomer sheet and the conductive path of the elastomer sheet to decrease over time, and therefore, as the local contact resistance value gradually increases, a It is something to do. However, in the anisotropically conductive elastomer sheet of the present invention, the conductor is electrically independent but mechanically acts as a face piece, so even if stress is locally applied, the stress inside the elastomer sheet remains unchanged. In addition, since the conductive fibers are reinforced by the weft yarns, deformation of the sides of the conductive fibers is less likely to occur. In addition, since the elastomer insulating layer existing as a matrix is integrated with the net in a state where it is visible, the ``elastomer insulating layer''
It has the advantage that peeling between the nets is less likely to occur, and because the nets are reinforced by the elasticity of the elastomer elastic screws, the shape stability is excellent, and deformation is extremely difficult to occur even when localized stress is applied. Therefore, the anisotropically conductive elastomer sheet of the present invention can be used repeatedly many times.
In addition, the reliability of the electrical connection is unlikely to be lost even during continuous use over a long period of time, making it possible to provide an extremely reliable connection. As described above, the anisotropic conductive elastomer sheet obtained by the present invention and the method for manufacturing the same eliminate the conventional drawbacks, further improve the reliability of the anisotropic elastomer sheet, and have high productivity at low cost.

層することもできる。The silicone rubber 4 was cured by exposure to ultraviolet light for 10 seconds using a mercury ultraviolet light lamp. Fifty sheets of heat-curable liquid resin (mm) were alternately laminated on the flat surface of the obtained net-rubber composite, and the mixture was heated under a pressure of 10 kg/am''.
It was cured by heating at 30°C for 3 hours. The obtained net-rubber composite block was sliced into YK thicknesses of 1 mm in the direction perpendicular to the longitudinal direction of the warp 1 to obtain an anisotropically conductive rubber sheet. This sheet has a conductive path density of 20 lines/mW.
As is clear from the above examples, according to the present invention, the conductive path density is 2 to 1 compared to the conventional method.
It is possible to produce an anisotropically conductive sheet (1) with an extremely high productivity without causing unevenness in the conductive path density. Furthermore, in the present invention, conductive fibers are used for the warp and insulating fibers are used for the weft, but it is clear that the same product as the present invention can be obtained even if the warp and weft are reversed depending on the manufacturing method. In the above examples, insulating layers were formed on both sides of a net made of conductive fibers and insulating fibers, but when obtaining a fiber-elastomer composite made of multiple laminated layers, one side of the net was used. A plurality of insulating layers may be formed and laminated together, or nets may be alternately laminated between the insulating layers and laminated together by an appropriate method.

等の効果を奏する。Furthermore, when forming the insulating layer, tension is applied to the conductive fibers of the net in the length direction of the conductive fibers to form a net-elastomer composite block in good condition.
However, this is to adjust the orientation of the conductive fibers, and another effect is that the insulating layer is made of elastomer, so the resulting net-nidistomer composite block is , an elastomeric insulating layer is compressed along the length of the conductive fibers. Under this condition, when the conductive fibers are sliced in a direction perpendicular to their length, they are released from the tension and expand, and the ends of the conductive fibers are relatively slightly buried in the insulating layer. . This makes it possible to arrange the switch directly on the fixed contact surface, resulting in effects such as extremely simplifying the configuration of the switch.
