<P>PROBLEM TO BE SOLVED: To provide an anisotropic conductive sheet and a board body capable of responding to micro-fabrication of a connected conductor and narrower pitch. Ž<P>SOLUTION: The board body B is formed by pasting the anisotropic conductive sheet 20 on a board 11. The anisotropic conductive sheet 20 uses a frame plate 21 made of porous PTFE. A tapered pierced hole is formed on the frame plate 21. A pierced conductive member 22 using non-electrolytic plating is formed on an inner wall section of the pierced hole. A board side conductor 15 and a mating conductor are conducted by sandwiching the pierced conductive member 22. In that case, a large diameter side of the tapered pierced hole is brought into contact with the board side conductor 15, and a small diameter side of the tapered pierced hole is brought into contact with the mating conductor. Generation of conduction failure, improper connection, and short circuit can be restrained even though the mating conductor is formed at micro-fabrication and narrower pitch.
