Abstract: A sealed battery includes a battery case with a bottomed cylindrical shape having an opening; an electrode body housed in the battery case; an electrolyte solution; and a sealing member that closes the opening of the battery case. The sealing member is formed by stacking a terminal cap, a bottom plate electrically connecting the terminal cap and an electrode of one polarity of the electrode body, and a valve body interposed between the terminal cap and the bottom plate. The valve body has a surface covered with a resin material, and an end surface that is an outer edge of the valve body is covered with a protective layer containing a compound A having corrosion resistance to the electrolyte solution.
