1. An anisotropic conductive sheet comprising:

  • a sheet body formed of a material having an insulation property, the sheet body having first and second side surfaces opposite to each other, and having a plurality of hole portions that each extend through the sheet body from an opening of the hole portion in the first side surface to an opening of the hole portion in the second side surface with the opening in the first side surface being wider than the opening in the second side surface; and

    a plurality of conductive portions corresponding, respectively, to the plurality of hole portions, whereineach conductive portion of the plurality of conductive portions extends in the corresponding hole portion of the plurality of hole portions from the first side surface to the second side surface, and includes a plurality of conductive fibrous members that are in contact with each other, to provide electrical contact through the conductive portion from the first side surface to the second side surface, andthe plurality of conductive fibrous members included in each conductive portion of the plurality of conductive portions longitudinally extend along a direction that is substantially parallel to a longitudinal axis of the corresponding hole portion of the plurality of hole portions.
