Claim 0:
1. A multilayer ceramic electronic component comprising:
a multilayer body including a plurality of layered ceramic layers and a plurality of layered inner electrode layers, a first main surface and a second main surface facing each other in a layering direction, a first side surface and a second side surface facing each other in a width direction orthogonal or substantially orthogonal to the layering direction, and a first end surface and a second end surface facing each other in a length direction orthogonal or substantially orthogonal to the layering direction and the width direction;
a first outer electrode covering the first end surface and extending from the first end surface so as to cover portions of the first main surface, the second main surface, the first side surface, and the second side surface;
a second outer electrode covering the second end surface and extending from the second end surface so as to cover portions of the first main surface, the second main surface, the first side surface, and the second side surface; and
an insulating layer continuously extending from a ceramic layer at the first main surface of the multilayer body so as to cover an end edge portion of the first outer electrode located on the first main surface of the multilayer body, and continuously extending from the ceramic layer at the first main surface of the multilayer body so as to cover an end edge portion of the second outer electrode located on the first main surface of the multilayer body; wherein
t2>t1 is satisfied, where t1 represents a dimension from a surface of the first main surface of the multilayer body to a first-main-surface-side surface of the insulating layer in the layering direction, and t2 represents each of a dimension from the surface of the first main surface of the multilayer body to a first-main-surface-side surface of the first outer electrode in the layering direction and a dimension from the surface of the first main surface of the multilayer body to a first-main-surface-side surface of the second outer electrode in the layering direction;
the insulating layer is provided only on the first main surface side of the multilayer body;
the first outer electrode includes a first underlying electrode layer and a first plating layer disposed on a surface of the first underlying electrode layer, and the second outer electrode includes a second underlying electrode layer and a second plating layer disposed on a surface of the second underlying electrode layer; and
the insulating layer covers end portions of the first underlying electrode layer and the second underlying electrode layer.
