Abstract:
A multilayer type electronic part including a laminated structure and a pair of external electrodes, the laminated structure being formed by stacking a plurality of first ceramic layers and two sets of one or more second ceramic layers, the first ceramic layers being provided with internal electrode patterns on top thereof, the second ceramic layers having no internal electrode pattern and the two sets of second ceramic layers being located at a top and a bottom portions of the laminated structure, respectively, the internal electrode patterns being connected to each other to form a coil inside the laminated structure, the laminated structure having a set of a top and a bottom surfaces opposing each other and a set of two opposing side surfaces, the top and the bottom surfaces corresponding to the outermost surfaces of the second ceramic layers, and the pair of external electrodes being provided at the two opposing surfaces of one of the two sets and connected to the coil, the multilayer type electronic part further comprising:one or more third ceramic layers, the third ceramic layers not including internal electrode pattern and being interposed between the first ceramic layers; andmeans for connecting the internal electrode patterns formed on the first ceramic layers to form the coil.
