Patent ID: 7405363

Claim:
A connecting sheet comprising a multilayer board constructed of plural boards that are laminated, a pair of external connecting terminals being in pressurized contact with two edges of the multilayer board, the multilayer board comprising: a first high speed transmission line board having a stripline structure, that comprises a first elastomer sheet that has a fixed dielectric constant; plural first elastomer strips arrayed at two edges of the first elastomer sheet, that are electrically conductive between front and back surfaces; and plural first high speed transmission lines connecting two ends of the plural first elastomer strips and being formed in a pattern on the first elastomer sheet; and a first surface layer board that comprises a second elastomer sheet that is nonconductive, and plural second elastomer strips arrayed in association with the plural first elastomer strips, at edges of the second elastomer sheet, being electrically conductive between front and back surfaces.
