A non-aqueous electrolyte secondary battery according to the present invention is characterized by including a non-aqueous electrolyte which contains at least one of vinylene carbonate derivatives at a concentration of 1 wt % or less and at least one of cyclic sulfates at a concentration of 2 wt % or less. When a received broadcast radio signal exceeds a quality parameter, that signal is sent to a speaker 56. The dielectric material layer is planarized to form a horizontal planar surface that is coplanar with a topmost surface of the selective conductive cap.
