Abstract
A laminated electronic component is configured to include substrate plating films disposed on outer surfaces of an electronic component main body through direct plating such that external terminal electrodes are connected to exposed portions of internal conductors (internal electrodes), and the average particle diameter of metal particles defining the substrate plating film is at least about 1.0 μm. The external terminal electrode includes at least one layer of an upper plating film disposed on the substrate plating film. The metal particles defining the substrate plating film are Cu particles.
Claims3
A method for manufacturing a laminated electronic component including an electronic component main body including a plurality of laminated functional layers, internal conductors which are disposed inside the electronic component main body and a portion of which are exposed at outer surfaces of the electronic component main body, and external terminal electrodes disposed on the outer surfaces of the electronic component main body so as to connect to the internal conductors and to cover the exposed portions of the internal conductors, the method comprising the steps of:
- forming a substrate plating film having an average particle diameter of metal particles of at least about 1.0 μm on the outer surfaces of the electronic component main body by direct plating so as to cover the exposed portions of the internal conductors and form the external terminal electrodes on the electronic component main body;
- forming an upper first plating film on the substrate plating film;
- and
- forming an upper second plating film on the upper first plating film;
- wherein
- the steps of forming the substrate plating film, forming the upper first plating film, and forming the upper second plating film are performed sequentially.
