Abstract
A multilayer ceramic capacitor includes a multilayer body including dielectric layers and electrode layers laminated therein, and two external electrodes respectively provided on two end surfaces of the multilayer body. As seen in a plane including a width and a lamination direction in a middle portion in a length direction, among the internal electrode layers, end portions in the width direction of about 90% or more of internal electrode layers in a middle in the lamination direction are curved toward a second main surface.
Claims19
A multilayer ceramic capacitor comprising:
- a multilayer body including a plurality of dielectric layers and a plurality of internal electrode layers laminated therein, a first main surface and a second main surface opposed to each other in a lamination direction, a first lateral surface and a second lateral surface opposed to each other in a width direction intersecting the lamination direction, and two end surfaces opposed to each other in a length direction intersecting the lamination direction and the width direction;
- and
- two external electrodes respectively provided on the two end surfaces of the multilayer body;
- wherein
- as seen in a plane including the width direction and the lamination direction in a middle portion in the length direction, among the plurality of internal electrode layers, end portions in the width direction of about 90% or more of internal electrode layers in a middle in the lamination direction are curved toward the second main surface;
- an end portion in the width direction of at least one of the plurality of internal electrode layers is not curved toward the second main surface;
- and
- the end portions in the width direction of all of the plurality of internal electrode layers are each aligned to be positioned in a range of about 3 μm in the lamination direction.
