<P>PROBLEM TO BE SOLVED: To provide a thin wall surface writing board in which the occurrence of surface irregularities such as wrinkles, bulges, or projections caused by thermal expansion or thermal shrinkage due to variation in ambient temperature, is prevented. <P>SOLUTION: This thin wall surface whiteboard 1 includes a board section 10, a frame section 20, and a frame cover section 30. Its back side is mounted on the wall surface 2 to be used as a wall, while its front surface is used also as a writing implement. The board section 10 has a trilaminar-structure constituted of a ground veneer 10a, a magnet sheet 10b and a whiteboard 10c. The frame section 20 is installed so as to cover the circumference of the board section 10, provided with a frame joint area 21 adhered to the wall surface 2 and a frame contact area 22 contacting surface of the whiteboard 10c. The whiteboard 10c is sandwiched between the magnet sheet 10b and the frame section 20, thereby it can avoid any occurrence of surface irregularities such as wrinkles, bulges or projections caused by thermal expansion or thermal shrinkage. <P>COPYRIGHT: (C)2013,JPO&INPIT |
