PROBLEM TO BE SOLVED : To provide a negative ion producing source without danger to human bodies and environment for general use at low cost, which does not require costly applied energy, produces negative ions by a phenomena close to a natural situation of producing negative ions, without need of a complex control device and without the risk of electric discharge and leakage; and to provide a production method.SOLUTION : Negative ions are produced by forming a coating film 1 comprising a ferroelectric material and an additive for assisting and enhancing the action of the ferroelectric material or an additive for solidifying a constituent material containing the ferroelectric material on the surface of a conductive base 2 having a projection/recess shape, connecting the conductive base to the earth or an antenna, continuously producing negative charge by electrical polarization caused in crystals of the ferromagnetic material placed in the coating film because of a variation of the input amount of kinetic and thermal energies of the object fluid, concentrating the negative ions on the surface of the coating film, and thereby giving electrons to the object fluid in contact with the surface of the coating film.COPYRIGHT : (C)2014, JPO&INPIT |
