PURPOSE: Stairs with a self-power generator is provided to produce electricity by converting kinetic energy into electric energy, and for people using the stairs to effectively work by the elastic force of the stairs. CONSTITUTION: Stairs with a self-power generator comprises stair landings(10), fixed ends(30), an elastic generating module(20), and a charging unit. The fixed ends are placed under the stair landings. The elastic generating module is formed between the stair landings and the fixed ends. The elastic generating module comprises the fixed ends, a rack gear, a pinion gear, an elastic unit, and a coil receiver. The elastic unit is connected between the lower part of the rack gear and the fixed end. The charging unit charges the electricity generated from the elastic generating module.
