Disclosed is a thermosetting conductive paste which is advantageous in that an external electrode for multilayer ceramic electronic part formed using the paste exhibits excellent bonding properties with an internal electrode and is suitable for mounting on a substrate or plating, achieving excellent electric properties (electrostatic capacity, tan &#x3b4;. A thermosetting conductive paste comprising: (A) metal powder having a melting point of 700&#xb0; C. or higher; (B) metal powder having a melting point of higher than 300 to lower than 700&#xb0; C.; and (C) a thermosetting resin.

Thermosetting conductive paste and multilayer ceramic part having an external electrode formed using the same

The present invention is intended to solve the problem of a conventional thermosetting conductive paste with respect to bonding-property between an internal electrode(s) and an external electrode(s) so as to provide a multilayer ceramic electronic part suitable for its mounting on a substrate and for its plating-treatment. The present invention relates to a multilayer ceramic electronic part, characterized in that it has an external electrode(s) formed from a thermosetting conductive paste comprising conductive particles having a high melting point, metal powder having a melting point of 300&#xb0; C. or less and a resin(s).

Electronic part with external electrode

There is disclosed a conductive adhesive comprising (A) conductive particles having a surface of at least one of nickel and nickel-boron alloy, and the surface of which has been subjected to surface treatment with a mixture of a polyoxyalkylene phosphate compound and a polyoxyalkylenealkyl or polyoxyalkylenealkenyl amine or a derivative thereof; (B) an epoxy compound which contains a diglycidyl epoxy compound used as a reactive diluent in an amount of 20 to 70 weight % based on the total amount of the epoxy compound; and (C) a phenolic resin hardener which contains at least one of an alkyl resol phenolic resin and alkyl novolak phenolic resin in an amount of 50% by weight or more based on the total amount of the phenolic resin hardener.
