PROBLEM TO BE SOLVED: To provide a board with a surface made of a material hard to slip in order to solve the problem that the keyboard of a personal computer is difficult to stably use because it is slippery at the time of using it on the knee, and to provide a board made of a thermal insulation material to solve that the coldness of the keyboard is transferred to the knee to give an uncomfortable feeling in a cold time such as winter. SOLUTION: A material hard to slip or a thermal insulation material 1 is stuck or applied to both sides of a core 2, whereby this board can be used with almost slippage, or the coldness can be hardly transferred to the board.
