Solid electrolytic capacitor and method of manufacturing solid electrolytic capacitor

A solid electrolytic capacitor includes an anode and a dielectric layer. The anode is made of niobium or a niobium alloy. The dielectric layer is made of niobium oxide formed on the niobium or the niobium alloy. The niobium oxide has a feature that a full width at half maximum of a peak of an Mz ray...

More Information
Summary:A solid electrolytic capacitor includes an anode and a dielectric layer. The anode is made of niobium or a niobium alloy. The dielectric layer is made of niobium oxide formed on the niobium or the niobium alloy. The niobium oxide has a feature that a full width at half maximum of a peak of an Mz ray of characteristic X-rays of niobium is 0.98 AA or more. The characteristic X-rays are emitted when the niobium oxide is irradiated with an electron beam.
