To improve visibility and to maintain a secure magnetization state by forming an extra area part between the outer peripheral edge of the part to be fixed to the magnet sheet body of a display board and the outer peripheral edge of this magnet sheet body.

The magnetized display board 1 is composed of the magnet sheet body 2, known as a magnet sheet, which is formed by alternately magnetized with N poles and S poles to a fine band form and is formed to a rectangular shape having flexibility, and the approximately T-shaped display board 3 which consists of a synthetic resin provided with a mounting part 3a in its base end part. A proper display area is formed on the front surface of such display board 3 in such a manner that characters, symbols, designs, etc., are stated thereon. An adhesive is applied over the entire apart of the rear surface of the mounting part 3a and the display board 3 formed with the fixing part 4 is adhered and fixed in an upright state to the surface of the magnet sheet body 2. At this time, the extra area part 5 which is not adhered is formed between the peripheral edge of the fixing part 4 and the outer peripheral edge of the magnet sheet body 2 and more particularly between the top end edge 2a of the magnet sheet body 2 and the fixing part 4.
