Abstract:
This anisotropic conductive sheet includes: a plurality of conductive paths; and an insulation layer which is disposed to fill the space between the plurality of conductive paths and has a first surface and a second surface. Each of the conductive path extends in a thickness direction of the insulation layer and has a first end part on the first surface side and a second end part on the second surface side. When the conductive paths are seen through so that the center of the first end part overlaps the center of the second end part, at least a portion of the conductive paths does not overlap the first end part and the second end part.
