The present invention relates to an triboelectric nanogenerator using an ionic elastomer that increases internal electric capacity and allows a large amount of electric charge to be located on a surface to generate a large amount of electrical energy. The triboelectric nanogenerator according to the present invention includes a first electrode; an ionic elastomer disposed on the first electrode and including an elastomer and an ionic liquid; a second electrode disposed to be spaced apart from the first electrode and electrically connected to the first electrode; and an insulator disposed under the second electrode, selectively contacting the ionic elastomer, and formed of a material that has a negative charge compared to the ionic elastomer. In this case, the ionic elastomer and the insulator are brought into contact with each other or are separated from each other by external force, and electrical energy is generated between the first and second electrodes when the ionic elastomer and the insulator are brought into contact with each other and separated from each other.
