Abstract: The fine water discharging element capable of transitioning between an adsorption state where water contained in a fluid to be treated is adsorbed and a discharge state where the adsorbed water is discharged to the fluid to be treated, the fine water discharging element comprising a base material portion, a plurality of particles and a nanochannel formed between the shell portions by laminating the plurality of particles on an outer surface of the base material portion in a rich viscoelasticity film shape. The fine water discharging element is transitioned between the adsorption state and the discharged state by changing the temperature of the water in the nanochannel by controlling an electrifying of at least one of the base material portion and the plurality of particles.

Abstract: A fine water discharge device includes a case having a flow path allowing a first space and a second space to communicate with each other, a blower which is disposed in the flow path, introduces air in the first space into the flow path, and discharges the air introduced into the flow path into the second space, a fine water generating unit which is disposed in the flow path and in which a plurality of the particles are laminated as a film-shaped conductive polymer film portion on an outer surface of a honeycomb member, and the particles are transitioned between an adsorption state where water is adsorbed and a discharge state where the adsorbed water is discharged to the air, an electrifying portion electrically connected to the honeycomb member to perform electrification, and a controller which is a control portion controlling the blower and the electrifying portion.
