Abstract: PROBLEM TO BE SOLVED: To improve rigidity and dispense with a special device such as a vibrator so as to reduce the size of a device as a whole by using a porous body having continuous pores and specifying porosity, a drain absorbing time, and a water absorbing height of the porous body. SOLUTION: In a molded body, continuous pores are formed continuously from one face to the other face, and its porosity is set to be 30-80%. If the porosity is 30% or less, a function as a porous body is hardly exhibited substantially, while the strength of the molded body tends to be lowered if the porosity is 80% or more. Either of uniform porosity or uneven porosity is adoptable as a whole of the element. A waterdrop absorbing time is set to 30 seconds or less, desirably, 10 seconds or less, and 5 seconds or less is more preferable. If the waterdrop absorbing time exceeds 30 seconds, a hydrophilic property cannot be obtained substantially. In addition, a water absorbing height is 5 mm or more per a minute, desirably, 10 mm or more, and 20 mm or more is more preferable.  If the water absorbing height is less than 5 mm per a minute, a hydrophilic property cannot be exhibited substantially.
