Abstract: A method of manufacturing a multilayer ceramic capacitor includes preparing a laminate including ceramic layers and internal electrode layers arranged in a stacking direction and including 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. The laminate includes two longitudinal end surfaces, and four surfaces orthogonal or substantially 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 transfer step, 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 capacitor includes a multilayer body having a dimensional relationship of the dimension in the width direction is greater than the dimension in the length direction which is greater than the dimension in the height direction. The dimension in the width direction of a third surface portion of a first external electrode is smaller than the dimension in the width direction of a first surface portion. The dimension in the width direction of an eighth surface portion of a second external electrode is smaller than the dimension in the width direction of a sixth surface portion. The dimensions in the height direction of a fourth surface portion and a fifth surface portion of the first external electrode are smaller than the dimension in the height direction of the first surface portion.

Abstract: A multilayer ceramic capacitor includes a multilayer body in which a dimension in a width direction >a dimension in a length direction >a dimension in a height direction is satisfied. A dimension in the length direction of each of lateral surface exposed portions is about 10% or more and about 44% or less with respect to the dimension in the length direction. A dimension of the external electrode in the length direction is about 17% or more and about 48% or less with respect to the dimension in the length direction.

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.
