Claim:
1. A thin film battery, comprising: a base substrate; a cathode current collector pattern and an anode current collector pattern being formed on the base substrate to be electrically separated from each other, wherein the cathode current collector pattern does not overlap the anode current collector pattern in a thickness direction of the substrate; a cathode pattern being formed on the cathode current collector pattern; an electrolyte pattern being formed on the cathode pattern, wherein the electrolyte pattern does not overlap the anode current collector pattern in the thickness direction of the substrate, wherein the cathode pattern is not fully covered the electrolyte pattern, and wherein the cathode current collector pattern does not contact with the electrolyte pattern; and an anode pattern being formed on the electrolyte pattern, wherein at least one pattern of the cathode current collector pattern or the anode current collector pattern comprises a non-noble metal based alloy, wherein the cathode current collector pattern comprises two sides each of which faces with a side of the anode current collector pattern, wherein the anode pattern comprises a protrusion portion, and wherein top surfaces of both the cathode current collector and the anode current collector are on the same plane.
