ABSTRACT:
One inventive aspect relates to a laminated capacitor capable of satisfying higher electrostatic capacitance and lower ESL at the same time. A dielectric chip constituting the laminated capacitor has an integral structure formed by alternately laminating a pair of first inner conductor layer and second inner conductor layer which are positioned on the same plane and are held in a non-contact relation, and a pair of third inner conductor layer and fourth inner conductor layer which are positioned on the same plane and are held in a non-contact relation, while a dielectric layer is interposed between the pair of first and second inner conductor layers and the pair of third and fourth inner conductor layers. Voltage of one polarity is applied to the first and fourth inner conductor layers from a first outer electrode through lead-out portions, and voltage of the other polarity is applied to the second and third inner conductor layers from a second outer electrode through lead-out portions.
