Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electrically anisotropic conductive adhesive sheet capable of enduring temperature change and capable of being used for burying an electrical module in a card main body. SOLUTION: This adhesive sheet used, especially, for bonding and joining the electrical module to the inside of the card main body is composed of at least one layer of an adhesive system which uses at least one kind of an adhesive capable of being thermally activated as a base material, wherein the adhesive system satisfies requisites (1) to (3) as follows: (1) a softening temperature of the adhesive system is positioned in a range of 65 to 165°C; (2) conductive particles are mixed with the adhesive system, wherein the particles have an average particle diameter of 25-100 μm (provided that the average particle diameter of the conductive particles is larger than a thickness of the layer of the adhesive system); and (3) the conductive particles have each a core of copper or zinc.
