An anisotropic conductive sheet interposed between a circuit board such as a substrate and various circuit parts to render them conductive and its manufacturing method. The anisotropic conductive sheet has a fine pitch required by the recent highly integrated circuit boards and electronic parts. In the anisotropic conductive sheet in which conductive members are scattered in a nonconductive matrix, the conductive members (e.g.,24) penetrate through the sheet (10) in the direction of thickness and conductive auxiliary layers (e.g.,25) are in contact with the conductive members (e.g.,24).
