发明名称 External electrode with an electroconductive resin layer for electronic component
摘要 The present invention aims to provide an electronic component capable of reducing the occurrence of cracks at the joining portion with a board etc. A capacitor 1 (laminated ceramic capacitor) being one example of the electronic component of the present invention is provided with an element assembly 10 (ceramic) and a pair of external electrodes 20 formed on both side surfaces of the element assembly. In the element assembly 10, a dielectric layer 12 and an internal electrode 14 are laminated alternately The external electrode 14 has such constitution that a first electrode layer connected with the internal electrode 14, a second electrode layer (electroconductive resin layer) including a hardened product of epoxy resin containing an epoxy compound having a molecular weight of 2000 or more and plural epoxy groups as the base compound, a third electrode layer composed of Ni and a fourth electrode layer composed of Sn are formed in this order from the element assembly side.
