PROBLEM TO BE SOLVED: To provide a magnet holder mounting an optional mounting outer peripheral surface out of a plurality of mounting outer peripheral surfaces to a plane body such as a bulletin board by the magnetic force of a permanent magnet movable in a storage chamber. SOLUTION: A notepaper holder includes a frame formed of a nonmagnetic material, and a holding part 40 provided at the frame to hold notepaper MP. At least a part of the outer peripheral part of the frame is formed of the plurality of mounting outer peripheral surfaces in order to be mounted to the plane body PL such as the bulletin board. The storage chamber 50 provided in the frame has a plurality of inner peripheral surfaces corresponding to the plurality of mounting outer peripheral surfaces respectively and stores the permanent magnet 3. The permanent magnet 3 is movably arranged in the storage chamber 50, and two attraction surfaces facing each other have magnetic poles. The attraction surfaces are set smaller than the respective inner peripheral surfaces to be located in contact with the respective inner surfaces. COPYRIGHT: (C)2011,JPO&INPIT
