PROBLEM TO BE SOLVED: To provide a board box allowing easy finding brake of a seal. SOLUTION: The board box 900 consists of an upper case 500 and a lower case 600 which are united and fixed by a male screw 400 in the interior of the outermost shell. A cover part 300 covers the male screw 400 in such a way that the cover must be broken if the operation to remove the male screw 400 is performed from outside. A fixing part 200 fixes the cover part 300 in such a way that the fixing part pierces a hole formed in the cover part 300 from one end and projects from the other end, and that the fixing part can be detached from the box only when the seal of the box is broken. Whether the seal of the board box 900 is broken or not can be easily determined by checking whether the cover part 300 is broken or not. COPYRIGHT: (C)2005,JPO&NCIPI
