Abstract
A negative electrode for an electrochemical capacitor includes a current collector having electric conductivity, and an electrode layer formed on a surface of the current collector and having cations stored therein. In at least a part of the electrode layer, a value of ratio I/Iof peak value Iindicating a presence of an anion decomposition compound and peak value Iindicating a presence of an electrolyte in a spectrum of an atom forming the anion is 0.45 or more and less than 2.55 as measured using X-ray photoelectron spectroscopy.
