An object of the present invention is to provide a humidifying device for humidifying a room, which can maintain a humidifying ability even if precipitates are generated on a moisture absorbing / releasing filter and does not require maintenance for a long period of time. SOLUTION: A moisture absorbing / releasing filter 11 in which an inorganic material 15 having a particle diameter of 2 μm to 55 μm is carried on a base material 13 having a gap 12 through which air can pass and the surface is made uneven has a moisture absorbing / releasing property on the surface. Therefore, it is possible to provide the moisture-absorbing / releasing filter 11 with less reduction in humidification ability due to adhesion of minerals. Further, the moisture absorbing / releasing filter 11 and the humidifier can be provided by using the moisture absorbing / releasing filter 11, which does not require maintenance for a long period of time.
