Publication number: 20210020378Abstract: In a multilayer ceramic electronic component, a stacked body includes a first outer layer and a first outermost internal electrode layer. The first outer layer defines a first main surface. The first outermost internal electrode layer is adjacent to the first outer layer. The first outermost internal electrode layer is in contact with a first external electrode at a first end surface. The thickness of the first outer layer at the first end surface is greater than the thickness of the first outer layer at the center or approximate center in a length direction.Type: ApplicationFiled: July 13, 2020Publication date: January 21, 2021Inventors: Takashi FUKUMA, Koji MORIYAMA
