PURPOSE: A fingerprint recognition sensor module using a multi layered electrode and a manufacturing method thereof are provided to make a thickness thin, and to make assemblage easy and lower price by reducing a number of components. CONSTITUTION: The module comprises a transparent substrate(100), a transparent electrode layer(120) formed on an upper part of the transparent substrate, a light emitting part(130) installed to the upper part of the transparent electrode layer, a lower electrode(140), the first insulation polymer(150), and the upper electrode(160). The lower electrode is installed around the light emitting part with a constant interval. The first insulation polymer is installed to the upper part of the lower electrode, and a part of the first insulation polymer overlaps/covers an end of the light emitting part. The upper electrode is installed to the upper side of the first insulation polymer.
