PROBLEM TO BE SOLVED: To prevent a ceramic electronic component from being mechanically damaged due to expansion and contraction of a wiring board, when the ceramic electronic component is mounted on the wiring board. SOLUTION: Terminal electrodes 5 is made to have respectively at least a three-layered structure, which is made by sequentially forming a first layer 7, a second layer 8 and a third layer 9 on both ends of an electronic component body 3. The second layer 8 has a porous structure by which the stress due to the expansion and contraction of a wiring board is advantageously absorbed, and stress is prevented from reaching the electronic component body 3. The first layer 7 which is not porous structure ensures good electrical conduction with inner electrodes 6. Similarly the third layer 9 which does not have porous structure prevents the penetration of plating liquid and ensures good electrical conduction with the outside. |
