Disclosed are a high-performance, inexpensive solid state thin film lithium ion secondary battery that is able to achieve charging and discharging in the atmosphere and can be manufactured at good yield and a manufacturing method therefor. A solid state thin film lithium ion secondary battery comprises an electrically insulating substrate (10) formed from an organic resin, an insulating film (20) that is formed from an inorganic material on the surface of this substrate, a cathode side collector film (30), a cathode active material film (40), a solid-state electrolyte film (50), an anode active material film (60), and an anode side collector film (70), which cathode side collector film and/or anode side collector film is/are formed on the surface of the aforementioned insulating film, wherein the thickness of the aforementioned insulating film is 10 nm or greater and 200 nm or less. The surface area of the aforementioned insulating film is greater than the surface area of the cathode side collector film or anode side collector film, or than the total surface area of the cathode side collector film and anode side collector film, and the aforementioned inorganic material contains at least one of either an oxide or nitride or sulfide containing any of Si, Al, Cr, Zr, Ta, Ti, Mn, Mg, or Zn. |
