Abstract

Official abstract text for this publication.

Provided is a novel electrically conductive adhesive which can yield a sintered body having low resistivity despite containing a thermosetting resin in addition to silver particles. This electrically conductive adhesive contains silver particles and a thermosetting resin. The silver particles are provided with a protective layer that contains a compound represented by general formula (1).[In general formula (1), R1 is an alkyl group having 1-5 carbon atoms, and R2 is a hydrogen atom or an alkyl group having 1-5 carbon atoms.]

First claim

Opening claim text (preview).

1 . An electrically conductive adhesive comprising: a silver particle; and a thermosetting resin, wherein the silver particle has a protective layer containing a compound represented by the following general formula (1): wherein R 1 represents an alkyl group having 1 to 5 carbon atoms; and R 2 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms. 2 . The electrically conductive adhesive according to claim 1 , wherein the thermosetting resin is an epoxy resin. 3 . The electrically conductive adhesive according to claim 1 , wherein the silver particle is contained in a content ratio of 70 mass % or more. 4 . The electrically conductive adhesive according to claim 1 , further comprising a solvent. 5 . The electrically conductive adhesive according to claim 4 , wherein the solvent has an octanol/water partition coefficient (Log Pow) of −2 or more and 4 or less. 6 . A sintered body of the electrically conductive adhesive according to claim 1 . 7 . An electronic component in which members are bonded with each other by the sintered body according to claim 6 . 8 . A method for manufacturing a sintered body, the method comprising a step of sintering the electrically conductive adhesive according to claim 1 at a temperature of 100° C. or more and 250° C. or less. 9 . A method for manufacturing an electronic component in which members are bonded with each other by a sintered body, the method comprising: a step of disposing the electrically conductive adhesive according to claim 1 between the members; and a step of sintering the electrically conductive adhesive at a temperature of 100° C. or more and 250° C. or less.
