<p>PROBLEM TO BE SOLVED: To prevent curing of an insulating adhesive even if accidentally heated before the use in an anisotropic conductive adhesive obtained by blending conductive particles in an insulating adhesive comprising a thermosetting resin. SOLUTION: This insulating adhesive 2 is composed of a thermoplastic resin (epoxy resin) blending a curing agent 4 coated with a covering film 5 in a main component (bisphenol A) 6. In usual states, the curing agent 4 coated with the covering film 5 can avoid contacting with the main component 6 and the covering film 5 can avoid to be destructed only by heating. Therefore, the insulating adhesive 2 can avoid to be cured even if accidentally heated before the use. On the other hand, when the adhesive is thermocompression bonded in the use, the curing agent 4 is contacted with the main component 6 by destroying the covering film 5 under the pressure, then the insulating adhesive 2 can be cured in the use.</p> |
