An anisotropic conductive sheet has an insulation layer having a plurality of through-holes and a plurality of conductive layers each arranged on an inner wall surface of each of the plurality of through-holes. Each of the conductive layers has a base layer arranged on the inner wall surface of each of the through-holes and a metal plating layer arranged so as to contact with metal nanoparticles or a metal thin film in the base layer or the metal thin film. The base layer includes metal nanoparticles or a metal thin film and a binder, wherein at least a portion of the binder is arranged between the inner wall of each of the through-holes and the metal nanoparticles or the metal thin film. The binder is a sulfur-containing compound having a thiol group, a sulfide group or a disulfide group.
