1. A triboelectric generator comprising:
a flexible electrode part comprising a first dielectric layer, a second dielectric layer, and at least one metal layer disposed between the first dielectric layer and the second dielectric layer; and
a fixed electrode part spaced apart from both sides of the flexible electrode part, and comprising a first electrode and a second electrode connected to each other,
wherein the flexible electrode part generates triboelectrification based on contact and non-contact with at least one of the first electrode or the second electrode by a fluid flow, and
an electric charge generated by the triboelectrification moves through the metal layer.
