PURPOSE: To provide a moving surface for a computer mouse comfortable to use without being bulky at an extremely low cost.

CONSTITUTION: This moving surface 1 for the computer mouse is placed on some operation plane and it is provided with a hard and rough flat upper part 2 formed by an antistatic material for surely moving the mouse and a nonskid lower part 3 to be in contact with the operation plane. Notably, the moving surface 1 is composed of a thin plate-like single component plastic material provided with at least one adhesive surface 3 on the lower surface, and by the adhesive surface 3, the moving surface 1 is maintained at a desired position and is directly stuck to the desired position. It is preferable that the single component material is transparent so as to view a pattern constituted by one or plural adhesive surfaces of prescribed color and shape while protecting it.
