Abstract
A multilayer ceramic electronic device having a dielectric body formed by stacking a plurality of dielectric sheets. Two types of internal electrodes are alternately arranged inside the dielectric body via dielectric sheets. Each internal electrode is formed with a lead part led out straddling three side surfaces of the dielectric body. Two terminal electrodes are arranged at outer surfaces of the dielectric body. Each terminal electrode is arranged at the outer surface of the dielectric body straddling three side surfaces of the dielectric body, is connected to either of the two types of internal conductors, and is insulated from the other. In this multilayer ceramic electronic device, the ESL can be greatly reduced. This multilayer ceramic electronic device is used for example as a decoupling capacitor.

A multilayer ceramic electronic device comprising:
- a dielectric body formed by stacking a plurality of dielectric sheets;
- two types of internal conductors arranged inside said dielectric body sandwiched between said dielectric sheets, formed with lead parts led out straddling three side surfaces of said dielectric body, and interposed between different layers;
- and
- two terminal electrodes each arranged at an outer surface of said dielectric body straddling three side surfaces of said dielectric body, covering the lead parts led out straddling three sides to be connected to one of the two types of internal conductors, and insulated from the other,
- wherein the lead parts of the two types of internal conductors led out to the side surfaces of the dielectric body are arranged straddling three side surfaces of the dielectric body in a positional relationship not overlapping but almost close to each other in a center portion of the dielectric body when projected in a stacking direction of said dielectric sheets such that areas in the two type of internal conductors where current flows in reverse directions are maximized.
