摘要： A multilayer electronic component includes a body including dielectric layers and internal electrodes alternately disposed in a first direction, and external electrodes disposed on the body to be connected to the internal electrodes. At least one internal electrode of the internal electrodes includes a plurality of disconnected portions penetrating through a respective internal electrode. A disconnected portion of the plurality of disconnected portions includes at least one of a pore or a dielectric substance disposed to connect adjacent dielectric layers to each other. A dielectric filling ratio, defined as a ratio of an overall length of the dielectric substance to an overall length of the disconnected portion on a cross section in the third and first directions, is more than 20% to 80% or less.
