| 1. A multilayer capacitor comprising:
a capacitor element body having rectangular first and second main faces opposing each other, first and second side faces extending
in a short side direction of the first and second main faces so as to connect the first and second main faces to each other
and opposing each other, and third and fourth side faces extending in a longer side direction of the first and second main
faces so as to connect the first and second main faces to each other and opposing each other, the capacitor element body including
a plurality of insulator layers laminated in the opposing direction of the first and second main faces;
a first terminal electrode arranged on the first side face of the capacitor element body;
a second terminal electrode arranged on the second side face of the capacitor element body;
a third terminal electrode arranged on the third side face of the capacitor element body;
a fourth terminal electrode arranged on the fourth side face of the capacitor element body;
a first inner electrode connected to the first terminal electrode and arranged within the capacitor element body;
a second inner electrode connected to the second terminal electrode and arranged within the capacitor element body; and
third and fourth inner electrodes connected to the third and fourth terminal electrodes and arranged within the capacitor
element body;
wherein the first and second inner electrodes have no overlapping area therebetween when seen in the opposing direction of
the first and second main faces and are arranged at respective positions different from each other in the opposing direction
of the first and second main faces and in the opposing direction of the first and second side faces;
wherein the third and fourth inner electrodes have no overlapping area therebetween when seen in the opposing direction of
the first and second main faces and are arranged at respective positions different from each other in the opposing direction
of the first and second main faces and in the opposing direction of the first and second side faces;
wherein the first and third inner electrodes have an overlapping area therebetween when seen in the opposing direction of
the first and second main faces; and
wherein the second and fourth inner electrodes have an overlapping area therebetween when seen in the opposing direction of
the first and second main faces.
