Since the number of slits 9 is small above the humidifier 1, the amount of evaporation is small. Further, since less humidifying water is consumed above the humidifying body 1, the amount of humidifying water supplied below the humidifying body 1 increases. Since more slits 9 are provided below the humidifying body 1 than above the humidifying body 1, evaporation of water below the humidifying body 1 can be promoted.

  • the effective water supply efficiency is a value calculated by dividing the amount of humidification by the amount of supplied water. Below the humidifier, the amount of humidification decreases as the amount of supplied water decreases.
  • the rate of decrease in the amount of humidification is smaller than the rate of decrease in the amount of supplied water. Therefore, the effective water supply efficiency increases below the humidifier where the opening is not provided.
  • many slits 9 are provided above the humidifier 1 . Therefore, when the humidifier 100 supplies less water than a humidifying body without openings, evaporation of water above the humidifying body 1 having a low effective water supply efficiency can be promoted. Further, since there are few slits 9 below the humidifier 1 where the effective water supply efficiency is high, the degree of moisture evaporation is smaller than above the humidifier 1 . Therefore, in this modified example, the amount of humidification below the humidifier 1 is reduced, and the effective water supply efficiency is reduced.
  • the humidifying body 1 according to the present modification has an effective water supply efficiency above the humidifying body 1 when the humidifying device 100 is less than a certain amount of water supplied. It is possible to suppress unevenness in the effective water supply efficiency in the lower part. That is, by averaging the effective water supply efficiency of the humidifying body 1 in the third direction Z of the humidifying body 1, the deposition amount of fine scale deposited by drying the humidifying body 1 can be averaged. Therefore, the life of the humidifier 1 can be extended.
