Disclosed is a writing board that has no edge-surrounding frame. This frameless writing board includes: a board main body (10) in which a front face of a base material section (12) is coated with a coating layer (14) and a side surface (14a) of the coating layer is formed to be stepped to be inside a side surface (12a) of the base material section; and a corner member (20) having a body portion (22) coupled with a corner of the board main body such that the corner of the board main body is not exposed to the outside and coupled by a hollow pin (22a) formed to be directed toward a back face penetrating the board main body and a body maintaining unit (24) coupled with the hollow pin in a state where the board main body is interposed and maintaining the body portion not to be separated from the board main body. Accordingly, the manufacturing unit costs and weight of the writing board can be reduced. |
