Abstract: A multilayer ceramic capacitor includes a multilayer body, and first and second external electrodes. The multilayer body further includes an extended dielectric portion extending from at least one of a first side margin portion and a second side margin portion to cover only a portion of an inner layer portion at at least one of a first end surface and a second end surface.

Abstract: An electronic component includes an element body including a stack and a side margin, the stack having a rectangular or substantially rectangular parallelepiped shape and including main surfaces opposing each other in a thickness direction, side surfaces opposing each other in a width direction orthogonal or substantially orthogonal to the thickness direction, and end surfaces opposing each other in a length direction orthogonal or substantially orthogonal to the thickness direction and the width direction, the stack including an internal electrode layer and a dielectric layer alternately stacked in the thickness direction, the side margin covering each of side surfaces of the stack in the width direction, and an external electrode covering one of the end surfaces of the element body in the length direction and electrically connected to the internal electrode layer.

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.

Abstract: A multilayer ceramic capacitor includes a multilayer body including an inner layer portion including dielectric layers and internal electrode layers, and external electrodes on end surfaces of the multilayer body. The internal electrode layers each include a counter electrode portion and an extension electrode portion extending from the counter electrode portion toward the end surface and, when viewing the multilayer body in a cross section parallel to the width direction and the lamination direction, and when a maximum length in the width direction of a range in which one end in the width direction of the counter electrode portions is provided is defined as R1, and a maximum length in the width direction of a range in which one end in the width direction of the extension electrode portions is provided is defined as R2, a relationship between R1 and R2 is R2>R1.
