Disclosed are triboelectric generators using surface plasmon resonance. A triboelectric generator includes first and second electrodes spaced apart from each other, first and second electrification layers provided on the first and second electrodes, respectively, and a light source provided to irradiate light onto the second electrification layer. Herein, the second electrification layer includes a metallic material configured to generate surface plasmon resonance due to light of a desired wavelength, and the light source irradiates the light of the desired wavelength configured to generate the surface plasmon resonance, onto the second electrification layer.
