PROBLEM TO BE SOLVED: To provide a board case capable of preventing fraudulence to a control board by a simpler structure. SOLUTION: The board case is structured to be held in the state with a case lid member attached to a case body member with a body side connection member 130 and a lid side connection member 240 engaged with each other and a body side engagement part 110 and a lid side engagement part 220 connected to each other, when the body side engagement part 110 and the lid side engagement part 220, facing each other, are superimposed on each other. The connection part 229a with the lid side engagement part 220 in a rotation restraining part 229 can be cut, and the case lid member can be detached from the case body member by releasing the engagement state between the body side connection member 130 and the body side engagement part 110, while cutting the connection part 229a with the lid side connection member 240 abutting on the rotation restraining part 229 by rotating the lid side connection member 240 together with the body side connection member 130 in the other direction at a first prescribed angle only.
