Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrodes alternately laminated therein, and two end surfaces opposing each other in a length direction, and two side surfaces opposing each other in a width direction, and two external electrodes respectively on the two end surfaces of the multilayer body. At least one of two opposed main surfaces of the multilayer ceramic capacitor includes raised portions provided respectively on one side and another side with a middle portion of the main surface interposed therebetween. The raised portions are each raised to become thicker in the lamination direction from the middle portion toward an outer periphery of the main surface.

Abstract: A multilayer ceramic capacitor includes end-surface external electrodes and side-surface external electrodes. The end-surface external electrodes are respectively provided at end surfaces of a multilayer body and are respectively connected to end-surface connecting internal electrodes. The side-surface external electrodes are respectively provided at the side surfaces of the multilayer body and respectively connected to side-surface connecting internal electrodes. The end-surface connecting internal electrodes each include end surface opposing portion opposing the side-surface connecting internal electrode 15B adjacent in a lamination direction, and an end surface lead-out portion extending from the end surface opposing portion to one of the end-surface external electrodes. The side-surface connecting internal electrodes each include a side surface opposing portion opposing the end-surface connecting internal electrodes adjacent in the lamination direction, and a side surface lead-out portion extending from the side surface opposing portion to one of the side-surface external electrodes.

Abstract: A multilayer ceramic capacitor includes a substantially rectangular parallelepiped multilayer body including dielectric ceramic layers and internal electrode layers laminated alternately in the lamination direction, first and second main surfaces opposed to each other in the lamination direction, first and second lateral surfaces opposed to each other in the width direction orthogonal or substantially orthogonal to the lamination direction, and first and second end surfaces opposed to each other in the length direction orthogonal or substantially orthogonal to the lamination direction and the width direction, and a pair of external electrodes at both ends of the multilayer body in the length direction to cover at least the first and second end surfaces, and connected to the internal electrode layers. A first protrusion is provided at each of four corners on a surface of at least one of the first and second main surfaces having a substantially rectangular shape.

Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and layered internal electrodes, first and second main surfaces, first and second side surfaces, first and second end surfaces, and an external electrode connected to the internal electrodes and provided on each of the first and second end surfaces. A region where the internal electrodes are superimposed is defined as an effective region, regions respectively located on sides of the first and second end surfaces relative to the effective region are defined as first and second regions, and a bent portion where the dielectric layers and the internal electrodes are bent is located in the first region. In the bent portion, all vertices in the stacking direction are located within a range that extends by about 25 μm to about 35 μm in a length direction from the effective region of the multilayer body.
