Title: Electrically conductive adhesive

Abstract: The present invention provides an electrically conductive adhesive which prevents migration and sulfuration of a metal component in electronic component mounting. The electrically conductive adhesive includes a thermosetting resin and metal filler particles dispersed in the thermosetting resin. It is possible to use, as the metal filler particles, metal filler particles having a composition including an alloy of Ag with at least one metal selected from the group consisting of Sn, Cu, In, Bi and Ni, a mixture of such metal filler particles and Ag filler particles, and metal filler particles including Ag filler particles and a coating layer formed on the surface of the Ag filler particles using a metal such as Sn.
