Abstract:
1. A monolithic ceramic capacitor comprising: a capacitor body including a plurality of ceramic layers laminated on one another, the plurality of ceramic layers including first to third ceramic layers, the capacitor body having first and second main surfaces facing each other, first and second side surfaces facing each other, and first and second end surfaces facing each other; a first internal electrode disposed in an interior of the capacitor body, the first internal electrode including a capacitance portion arranged to form a capacitance and a lead-out portion lead out from the capacitance portion to the first end surface; a second internal electrode disposed in the interior of the capacitor body, the second internal electrode including a capacitance portion arranged to form a capacitance and a lead-out portion lead out from the capacitance portion to the second end surface, the second internal electrode being electrically insulated from the first internal electrode via the first ceramic layer; a third internal electrode disposed in the interior of the capacitor body, the third internal electrode including a capacitance portion arranged to form a capacitance and a lead-out portion lead out from the capacitance portion to the first end surface, the third internal electrode being electrically insulated from the second internal electrode via the second ceramic layer, the third internal electrode being arranged at a position different from that of the first internal electrode in a direction in which the ceramic layers are laminated; a first external terminal electrode disposed on the first end surface of the capacitor body, the first external terminal electrode being electrically connected to the first internal electrode and the third internal electrode; and a second external terminal electrode disposed on the second end surface of the capacitor body, the second external terminal electrode being electrically connected to the second internal electrode, the second external terminal electrode being connected to a potential different from that of the first external terminal electrode; wherein a size of the first end surface and the second end surface in a two-dimensional surface in which the ceramic layers extend is greater than a size of the first side surface and the second side surface in the two-dimensional surface in which the ceramic layers extend; the first external terminal electrode and the second external terminal electrode include a resistive component; in each of the first internal electrode and the third internal electrode, a width-direction size of the lead-out portion measured in a direction substantially parallel to the first end surface is less than a width-direction size of the capacitance portion measured in the direction substantially parallel to the first end surface; and the lead-out portion of the first internal electrode and the lead-out portion of the third internal electrode are located so as to partially overlap each other when viewed in the direction in which the ceramic layers are laminated.
