PROBLEM TO BE SOLVED: To provide a humidifier capable of improving both liquid-retaining performance and vaporization performance of a vaporization filter, reducing usage of the vaporization filter and realizing its small-sized product.SOLUTION: A humidifier of this invention has a vaporization filter, the vaporization filter is constituted by overlapped several base members 47A, 47B and 47C, each of the several base members 47A, 47B and 47C is constituted by a sewn member 63 provided on one surface thereof which has an aeration opening, and a fibrous member 64 provided on the other surface thereof which is composed of a fibrous cluster, and, in both surfaces of the vaporization filter, at least one surface is formed by the fibrous member 64. In this case, since one surface of each of the base members 47A, 47B and 47C is opened into a substantial ring-shape by the sewn member 63, it may be applicable to keep water-retaining performance when the vaporization filter absorbs water. In turn, the other surface of each of the base members 47A, 47B and 47C has its extremity end opened by the fibrous member 64 and shows superior releasable aqueous performance and subsequently superior vaporization performance. The vaporization filter has a structure making the best use of each of the elements. |
