1. An anisotropic conductive sheet comprising:
an insulation layer with elasticity including a first surface located on one side in a thickness direction, a second surface located on another side in the thickness direction, and a plurality of through holes extending between the first surface and the second surface; and
a plurality of conductive layers disposed at inner wall surfaces of the plurality of through holes,
wherein the insulation layer includes:
an elastic body layer comprising a cross-linked elastomer composition, and
a heat-resistant resin layer comprising a heat-resistant resin composition with a glass transition temperature higher than that of the cross-linked elastomer composition.
