Adhesive, electrode-connecting structure, and method of connecting electrodes

摘要

An adhesive which is for use in electrically connecting electrodes facing each other and comprises: (a) at least one cationically photopolymerizable compound selected among epoxy compounds, vinyl ether compounds, and cyclic ether compounds; (b) a cationic photopolymerization initiator such as an onium salt; (c) at least one radical-photopolymerizable compound selected among acrylic ester compounds, methacrylic ester compounds, and maleimide compounds; and (d) a free-radical photopolymerization initiator such as an organic peroxide.
