Anisotropic conductive sheet, manufacturing method thereof, and product using the same

There is provided an anisotropic conductive sheet capable of surely achieving a predetermined electrical connection even with an object having a very small arrangement pitch of electrodes to be connected, a manufacturing method thereof, and a product using the anisotropic conductive sheet. The anisotropic conductive sheet includes: an insulation sheet made of elastic polymer material having a plurality of conductive path forming through holes extending in the thickness direction; and a conductive path elements arranged as a unitary block with the respective conductive path forming through holes of the insulation sheet. An exposure mask used has a plurality of light transmitting through holes each having a diameter reduced from a first surface toward a second surface and formed according to a pattern corresponding to the pattern of the conductive path elements to be formed. The conductive path forming through holes are formed by applying a laser beam via the light transmitting through holes from the second surface of the exposure mask.
