A fine water discharge device comprising: a case which has a flow path allowing a first space and a second space to communicate with each other; an air blowing unit 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, includes a base material portion and a plurality of particles having a core-shell structure including a core portion forming a nucleus and a shell portion formed of a polymer material having a polar functional group capable of hydrogen bonding to cover the core portion, and in which at least one of the base material portion and the particles has conductivity, the plurality of the particles are laminated in a film shape on an outer surface of the base material portion, and states of 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 to generate fine water; an electrifying portion electrically connected to the base material portion of the fine water generating unit to electrify the base material portion; and a control portion which controls the air blowing unit and the electrifying portion, wherein the control portion includes a discharge control portion which executes a discharge mode of introducing the air in the first space into the flow path by the air blowing unit, electrifying the base material portion of the fine water generating unit by the electrifying portion to discharge the water adsorbed on the particles of the fine water generating unit to the air introduced into the flow path as an uncharged fine water cluster having a particle size of 50 nanometers or less through an opening of a channel formed by the plurality of laminated particles, and discharging the fine water to the second space together with the air introduced into the flow path by the air blowing unit, and a discharge preparation control portion which executes a discharge preparation mode of introducing the air in the first space or the second space into the flow path by the air blowing unit and non-electrifying the base material portion by the electrifying portion to adsorb the water introduced into the flow path to the particles through the channel from the opening. a case which has a flow path allowing a first space and a second space to communicate with each other; an air blowing unit 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, includes a base material portion and a plurality of particles having a core-shell structure including a core portion forming a nucleus and a shell portion formed of a polymer material having a polar functional group capable of hydrogen bonding to cover the core portion, and in which at least one of the base material portion and the particles has conductivity, the plurality of the particles are laminated in a film shape on an outer surface of the base material portion, and states of 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 to generate fine water; an electrifying portion electrically connected to the base material portion of the fine water generating unit to electrify the base material portion; and a control portion which controls the air blowing unit and the electrifying portion, wherein the control portion includes a discharge control portion which executes a discharge mode of introducing the air in the first space into the flow path by the air blowing unit, electrifying the base material portion of the fine water generating unit by the electrifying portion to discharge the water adsorbed on the particles of the fine water generating unit to the air introduced into the flow path as an uncharged fine water cluster having a particle size of 50 nanometers or less through an opening of a channel formed by the plurality of laminated particles, and discharging the fine water to the second space together with the air introduced into the flow path by the air blowing unit, and a discharge preparation control portion which executes a discharge preparation mode of introducing the air in the first space or the second space into the flow path by the air blowing unit and non-electrifying the base material portion by the electrifying portion to adsorb the water introduced into the flow path to the particles through the channel from the opening.
