According to the present invention, in the powder contact-type electrification generator, by placing the powder to be charged at the time of contact with the inside of the housing and generating the asymmetrical potential difference between the electrodes positioned above and below the housing as the charged fluid moves, Can be more easily converted into electric energy. It is also possible to increase the durability of the contact charging generator by using powder that is not a solid planar structure by using one of the two large bodies required for contact charging and by using a fluid that is relatively more movable relative to the external physical stimulus, . In addition, since the powder for contact charging inside the housing is easily contacted and separated from the inner wall of the housing by external physical stimulation such as wind by forming a ventilation hole capable of ventilating in the housing from the powder contact charging electric power generator,
