An anisotropic conductive adhesive sheet comprising at least a curing agent, a curable insulating resin and conductive particles, wherein in a region extending from a one-side surface of the anisotropic conductive adhesive sheet along the thickness direction to a position of not greater than 2.0 times the average diameter of the conductive particles, 90% or more of the sum of conductive particles are present, the 90% or more of the sum of conductive particles being present without contact with other conductive particles, and wherein the average diameter of conductive particles is in the range of 1 to 8 mum, the average particle distance between adjacent conductive particles being in the range of 1 to 5 times the average particle diameter and not greater than 20 mum, and wherein the thickness of the anisotropic conductive adhesive sheet is at least 1.5 times the average particle distance but not greater than 40 mum.
