ABSTRACT:
In a multilayer capacitor, widths of lead conductors of internal electrode and widths of lead conductors of internal electrode in an ESR control section are smaller than any one of widths of internal electrode and widths of internal electrode in a capacitance section. This narrows cross sections of the conductor portions connecting between the internal electrodes and the external electrodes, so as to her increase ESR. The widths of the respective lead conductors in the ESR control section are wider than widths of respective lead conductors in the capacitance section. This effectively prevents open failure and improves a yield of products.
