Patent ID: 6849335

Claim:
An anisotropically conductive sheet, comprising: a sheet base comprising an elastomer; and conductive particles exhibiting magnetism, said conductive particles being contained in the sheet base in a state oriented so as to arrange in rows in a thickness-wise direction of the sheet base, and dispersed in a plane direction of the base sheet, wherein supposing that a volume resistivity in the thickness-wise direction of said base sheet under an underpressurized state is R 0 , and a volume resistivity in the thickness-wise direction in a state pressurized under a pressure of 1 g/mm 2 in the thickness-wise direction is R 1 , the volume resistivity R 1 is 1×10 7 to 1×10 12 Ω·m, and a ratio (R 0 /R 1 ) of the volume resistivity R 0 to the volume resistivity R 1 is 1×10 1 to 1×10 4 .
