摘要：
A humidity detection material includes oxide of at least one metal selected from the group consisting of Mg, Ca, Mn, Fe, Co, Ni, and Cu. The metal oxide is preferably in the form of a porous material. The metal oxide is formed preferably in the form of a thin film on a transparent substrate. The humidity detection material is contacted with water vapor in the presence of a gas such as air, and the optical absorbance of the humidity detection material is measured to detect the humidity. The humidity can be detected by an optical method.
