A multilayer electronic component manufacturing method includes forming a multilayer body including a plurality of ceramic layers, and forming an outer electrode conductor layer on a bottom surface of the multilayer body. The method further includes forming a groove by removing at least a part of the outer electrode conductor layer in a part of the outer electrode conductor layer and a part of the bottom surface of the multilayer body after the outer electrode conductor layer is formed, and segmenting the multilayer body by dividing the multilayer body into a plurality of chip regions.
