Abstract
In order to provide an anisotropic conductive adhesive agent which is capable of including a predetermined number of conductive particles between the terminals to be connected in a sure manner and which improves the conductive reliability, a plurality of conductive particles included in the insulating adhesive agent of the anisotropic conductive adhesive agent are non-uniformly provided on the one side of the two adhering surfaces of the insulating adhesive agent . At the time of positioning the anisotropic conductive adhesive agent between the two terminals, if the adhering surface, which is the one to which the conductive particles are non-uniformly provided, is disposed to the side of the terminal, which is the one having a smaller dimension of protrusion toward the adhesive side of two terminals, it prevents the conductive particles , which are not positioned there, from being pressed out, even in the case that the insulating adhesive agent is pressed out toward a lateral side by the terminals having a greater dimension of protrusion, at the time of thermal compression bonding. Accordingly, a predetermined number of conductive particles can be included between each of the terminals, thereby improving conductive reliability.
