To provide a fixing structure for preventing bolts and screws from loosening even if a panel is fixed to a structure for receiving vibration by the bolts and screws.
In a method for fixing the panel A to a fixing member B, such as a building frame, by the bolts 1 and screws 1', a washer 3 in which a recess 5 is formed at the center corresponding to the head section of the bolts and screws is subjected to rotation-stop fixation to the panel at the mounting position of the bolts and screws to the panel A, the shank of the bolts and screws is inserted into a passage hole 6 open at the center of the recess 5 of the washer 3 for fixation, and a rotation-stop member 8 is filled into the gap between the recess 5 and the head periphery of the bolts 1 and the screws 1', thus preventing the loosening of the bolts and screws.
