CONDUCTIVE ADHESIVE AND CONDUCTIVE ADHESIVE-CURED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a conductive adhesive used for obtaining an electric connection with a tin-based conductive member, and capable of maintaining a good conductivity even under a high temperature and high humidity environment. SOLUTION: This conductive resin contains a thermosetting resin and metal powder, wherein the metal powder has≤0.815 sphericity and≥1.50 m2/g specific surface area and the content of the metal powder is selected so as to become 78-92 wt. % weight ratio in the cured product. It is preferable to have≤64 ppm ammonium ion extracted from the cured product of the components obtained by removing the metal powder from the conductive adhesive. Also, the conductive adhesive-cured product 11 formed on the surface of a conductive member 10 by using the conductive adhesive has preferably≤0.5 % rate of swelling and≤300 nm mean distance between the metal powder and the conductive member 11.
