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.
