PURPOSE: A self-adhesive board including electrodes is provided to conveniently attach and detach paper without using adhering materials. CONSTITUTION: A self-adhesive board comprises a body(10), a first electrode(20), a second electrode(30), a board(40), and a power supply device(50). The body is made of a flat board shaped insulator and has predetermined rigidity. The first electrode is formed throughout the front side of the body. The second electrode is formed to be spaced from the first electrode at a predetermined distance. The power supply device supplies power with different polarities to the first electrode and the second electrode. The polarities are alternately changed at a predetermined cycle. The board is located on the front side of the first electrode and the second electrode and covers the entire front area of the body. |
