Abstract
The present invention provides a conductive adhesive having excellent electrical conductivity and adhesiveness without using other additives. The conductive adhesive contains a compound expressed by general formula (1) (X1, X2, X3 and X4 are each independently hydrogen atom or a straight-chain alkyl provided that at least one of X1, X2, X3 and X4 is a 3-8C straight-chain alkyl and the others are each hydrogen atom, methyl group or ethyl group; eight R groups are each independently hydrogen atom, methyl group or ethyl group; and Y is a group containing at least one substituted or unsubstituted aromatic hydrocarbon ring.
Description
technical field [0001] The present invention relates to a conductive adhesive. Background technique [0002] In various devices, a conductive adhesive is sometimes used to join members constituting a conductive portion. Generally, a resin binder in which conductive particles such as metal particles and carbon particles are mixed can be used as the conductive adhesive. [0003] In order to electrically connect members using the conductive adhesive, it is generally necessary to bring the members closer to each other by pressing one member toward the other member in a state where the conductive adhesive exists between the members. The above-mentioned members are electrically connected to each other by means of conductive particles in the conductive adhesive. [0004] However, if a mechanically weak member is used as the members to be joined, when one member is pressed against the other, there is a problem that the members themselves cannot withstand the pressing force and the...
