Patent ID: 7419387

Claim:
An electric connection member for providing an electric continuity between a pair of objects, comprising: a first anisotropically conductive sheet and a second anisotropically conductive sheet, wherein the first anisotropically conductive sheet includes: a first electrically insulating elastomer sheet; first elastomer regions formed on said first electrically insulating elastomer sheet at a predetermined pitch; second elastomer regions formed at a predetermined pitch on said first electrically insulating elastomer sheet, wherein each of said first elastomer regions and said second elastomer regions is formed of electrically conductive elastomer, and said first elastomer regions are arranged at a pitch different from a pitch at which said second elastomer regions are arranged, and wiring patterns which enable electric connection between said first elastomer regions and said second elastomer regions, wherein the second anisotropically conductive sheet includes: a second electrically insulating elastomer sheet; and third elastomer regions that are arranged at a predetermined pitch on said second electrically insulating elastomer sheet and electrically conductive, wherein said first anisotropically conductive sheet and said second anisotropically conductive sheet are bonded together, and wherein the first elastomer regions and the third elastomer regions are arranged at a common pitch, and the third elastomer regions are securely in contact with the first elastomer regions by bonding so as to reinforce electric continuity.
