PROBLEM TO BE SOLVED: To provide a measuring box of a raw material measuring/supplying board which measuring box has a simple structure to prevent a raw material from sticking to the inner wall surface of the measuring box. SOLUTION: In the interior of the cylindrical measuring box 30, the area of a lower surface is determined to be larger than that of an upper surface. Specifically, the cylindrical measuring box 30 is shaped in such a way that the diameter of a lower opening is determined to be longer than that of an upper opening so that the interior of the measuring box 1 has an inversely tapered shape widening from the upper surface to the lower surface. This prevents the raw material from remaining stuck to the inner wall surface of the measuring box 1 after filling the law material into the measuring box 1 and measuring the law material. Adopting stainless steel or fluoride resin as the material of the inner wall surface of the measuring box 30 prevents sticking of the raw material efficiently. COPYRIGHT: (C)2006,JPO&NCIPI
