Abstract
Provided is a multilayer ceramic capacitor in which short-circuiting does not easily occur between internal electrodes adjacent to each other in the stacking direction. This laminated ceramic capacitor (1) is provided with: a laminated body (2) having alternately laminated dielectric bodies (14) and internal electrodes (15); and external electrodes (3) respectively disposed on a first end surface (Ca) and a second end surface (Cb) respectively provided on both sides of the laminated body (2) in the longitudinal direction (L) intersecting the lamination direction (T), the internal electrode (15) having: a facing portion (15a); a thick section (15b) that extends from the facing section (15a) to either the first end surface or the second end surface, is connected to the external electrode, and is thicker than the facing section in the lamination direction; and a thin portion (15c) that extends from the facing portion (15a) toward the other of the first end surface and the second end surface, is not connected to the external electrode, and has a thickness smaller than that of the facing portion in the lamination direction.
Description
Technical field [0001] The present invention relates to a laminated ceramic capacitor. Background technique [0002] In recent years, large-capacity and small laminated ceramic capacitors have been required. Such a laminated ceramic capacitor has a configuration in which an external electrode is disposed at both ends of the laminated body. [0003] The laminated body is alternately laminated with a layered dielectric and an internal electrode. The internal electrode includes a counter-opposite portion opposed to each other, and an lead portion extending from one of the outer electrodes of one or the other side, the length direction is shorter than the dielectric. Further, the lead portion is alternately configured from the internal electrode and the lead portion extending from the opposing portion to the opposing portion from the opposing portion to the other end surface. [0004] Thus, although the opposing portion of the interior electrode adjacent to each other is overlapped i...
