Abstract: A varistor includes a sintered body, an internal electrode, an insulating layer, and an external electrode. The internal electrode is disposed in an interior of the sintered body. The insulating layer covers at least part of the sintered body and includes Zn2SiO4. The external electrode is electrically connected to the internal electrode, covers part of the sintered body and part of the insulating layer, and is in contact with the part of the insulating layer. The insulating layer has a region being in contact with the external electrode, the region having a greater average thickness than a region of the insulating layer which is out of contact with the external electrode.

Abstract: A sintered body that includes ceramic layers and an internal electrode which are alternately stacked on one another is prepared. A first external electrode is formed on a side surface of the sintered body such that the first external electrode is connected to the internal electrode. An insulating layer is formed on a surface of the sintered body by applying a glass coating over an entire of the sintered body having the formed first external electrode. The insulating layer is exposed from the first external electrode. A second external electrode is formed on the first external electrode. This method provides the produced multilayer electronic component with a stable electric connection between the internal electrodes and the external electrodes.
