ABSTRACT:
An anisotropic conductive sheet capable of transmitting high-speed digital signals reliably is provided. The anisotropic conductive sheet has a conductive property in a thickness direction thereof under a predetermined condition, and includes: insulative matrix members having a dielectric constant value of at most 2.28 and a dielectric loss value of at most 0.025; and conductive members having a conductive property in the thickness direction under the predetermined condition in the conductive members capable of flowing electricity between top and bottom surfaces thereof are located in a scattered manner in the matrix members, and the conductive and matrix members are bonded chemically. Especially, the matrix member is made from a resin material having a resin foamed body of a foaming structure, i.e. homogeneous microcell structure. At least one of the conductive members may be of conductive elastomer.
