Multilayer ceramic electronic component including an insulating layer

A multilayer ceramic electronic component comprising:

• a calcined multilayer body including a plurality of layered ceramic layers and a plurality of inner electrode layers layered on the ceramic layers, a first main surface and a second main surface facing each other in a layering direction, 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 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 the length 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;
• and
• 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;
• wherein
• an insulating layer is provided only on a surface of the first main surface of the calcined multilayer body;
• a thickness of the insulating layer is less than or equal to about 5 μm;
• the first outer electrode and the second outer electrode disposed on the first main surface side are disposed on the insulating layer;
• and
• the insulating layer is made of a ceramic including a ceramic material as a main material.
