Abstract: An electrode mixture includes a sulfide solid electrolyte and a carbon-containing material having contact with the sulfide solid electrolyte. An intensity ratio C/S determined from a spectrum obtained by analyzing the electrode mixture by Auger electron spectroscopy satisfies 0.2≤C/S≤1, where C is an intensity of a peak in the spectrum which corresponds to carbon included in the carbon-containing material, and S is an intensity of a peak in the spectrum which corresponds to sulfur included in the sulfide solid electrolyte.
