Abstract
A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers alternately laminated, and external electrodes each on a corresponding one of end surfaces in a length direction perpendicular or substantially perpendicular to a lamination direction of the multilayer body, and each connected to the internal electrode layers. A surface, in a plan view in the length direction, of each of the external electrodes is covered with an insulating layer except for a frame region having a width of about 1 μm or more and about 100 μm or less from an outer peripheral edge of the surface.
Claims18
A multilayer ceramic capacitor comprising:
- a multilayer body including a plurality of dielectric layers and a plurality of internal electrode layers laminated;
- and
- external electrodes each on a corresponding one of end surfaces in a length direction perpendicular or substantially perpendicular to a lamination direction of the multilayer body, the external electrodes each being connected to at least one of the plurality of internal electrode layers;
- wherein
- a surface, as viewed in the length direction, of at least one of the external electrodes is covered with an insulating layer except for a frame region having a width of about 1 μm or more and about 100 μm or less from an outer peripheral edge of the surface;
- and
- the insulating layer has a thickness of about 200 μm or less in the length direction, and includes a thickest portion in a central region as viewed in the length direction.
