Abstract: A method of manufacturing a multilayer ceramic capacitor includes preparing a laminate by providing ceramic layers and internal electrode layers arranged in a stacking direction, and providing two or more exposure regions at which the internal electrode layers and the ceramic layer interposed between the internal electrode layers are both exposed, and transferring a first conductive paste to the laminate. In the preparing, forming the laminate to have a rectangular parallelepiped configuration or shape and to include two longitudinal end surfaces, and four surfaces orthogonal to the end surfaces and, on at least one of the four surfaces, a protrusion in which the exposure region protrudes outward. In the transferring, the first conductive paste is applied to a transfer jig including a groove, and the first conductive paste in the groove is transferred to a surface of the protrusion.

Abstract: A multilayer ceramic electronic component includes a laminated body, a first external electrode, a pair of second external electrodes, and a pair of insulating coating portions. The pair of insulating coating portions extends in a laminating direction between each of the pair of second external electrodes and the first external electrode on a second principal surface, from the second principal surface to respective portions of a first side surface and a second side surface. A maximum thickness of the first external electrode on the second principal surface is larger than a maximum thickness of the pair of second external electrodes on the second principal surface. The maximum thickness of the pair of second external electrodes on the second principal surface is larger than a maximum thickness of the pair of insulating coating portions on the second principal surface.
