PURPOSE: A sign board is provided, of which a flexible edge where bulletin contents is printed can easily be mounted and flexibly be maintained on a front or a front and a back of a frame. CONSTITUTION: The sign board comprise a frame, formed by assembling a frame member having a constant section shape, in which a slit and a support chin are formed; a tension member, installed on any side and supported by the supporting chin, in which at one and more slits are formed on an external side; and a flexible edge, supported by inserting a girth thereof into the slits, of which a position can be controlled to the direction of length of the slits with the supported state. Therefore, fabricating cost of a frame is not paid, a flexible edge can easily be replaced and reused to reduce environmental contamination, and the edge has the same elastic force to fabricate a strong sign board.
