Claim 4:
5. A method for using the humidity control element according to claim 1, comprising:
in a dehumidification and regeneration switching operation of repeating a dehumidification operation in which a fluid to be dehumidified flows into the dehumidifying flow path and flows out from the dehumidifying flow path, and a regeneration operation in which a regenerating fluid flows into the dehumidifying flow path and flows out from the dehumidifying flow path,
relating to a dehumidification amount of the dehumidifying flow path, and a switching time which is a switching interval of the dehumidification and regeneration switching operation,
in terms of change characteristics of a dehumidification amount which is decreased according to an increase in the switching time,
setting the switching time to the switching time at which the dehumidification amount falls between a maximum value of the dehumidification amount and a lower limit dehumidification amount which is a dehumidification amount reduced by 10% from the maximum value.
