PURPOSE: A strong signboard is provided to endure any impacts applied by the fisting and the kicking of any person, to extend the life of use thereof, and to improve the transmissivity of the signboard. CONSTITUTION: For improving the strength of an acryl signboard, a transparent soft vinyl is interposed between a first acryl member and a second acryl member by using a coating method. After the two acryl members are stacked into one acryl member, a transparent soft vinyl is repeatedly coated onto the top surface of acryl member onto which any letters are indicated. Thereby, the signboard is able to endure any strong impact by virtue of the cohesive force between the acryl members and the vinyl.
