Abstract:
1. A light emitting device comprising a semiconductor light-emitting element and a multilayer chip varistor, the multilayer chip varistor comprising: a laminate having a varistor layer comprised essentially of ZnO, and a plurality of internal electrodes arranged to sandwich the varistor layer between the internal electrodes; and a plurality of external electrodes formed on an outer surface of the laminate; wherein each external electode of the plurality of external electrodes is connected to a corresponding internal electrode of the plurality of internal electrodes; the semiconductor light-emitting element comprising: an electroconductive substrate of ZnO or GaN; and a pair of semiconductor layers of ZnO or GaN formed by epitaxial growth on two surfaces of the electroconductive substrate; wherein the semiconductor light-emitting element is disposed on an outer surface of the multilayer chip varistor parallel to a stacking direction of the internal electrodes of the multilayer chip varistor, and wherein one of the pair of semiconductor layers is fixed in face contact to the outer surface of the multilayer chip varistor.
