<P>PROBLEM TO BE SOLVED: To provide a ceiling base material hardly causing the fall of sticking liquid drops to prevent the fall of liquid drops from damaging a stored object or the like existing under the ceiling base material used in such an environment that the liquid drops of dew condensate or the like stick to the surface. <P>SOLUTION: The ceiling base material used inclining with respect to a horizontal plane has a liquid drop fall preventing surface on at least one surface of the base material. The liquid drop fall preventing surface has a function of allowing the sticking liquid drops to flow to the inclined lower side of the base material and dividing the flow of the liquid drops. <P>COPYRIGHT: (C)2010,JPO&INPIT |
