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. |
