A mouse pad structure includes a pad, a light source module, a control member, and a bendable wire. The light source module is installed in the pad. The control member is disposed corresponding to the pad. One end of the bendable wire is electrically connected to the light source module, the other end of the bendable wire is electrically connected to the control member, the bendable wire is provided for adjusting a distance between the control member and the pad. Accordingly, by collapsing or unfolding the bendable wire, the control member and the pad are spaced apart by a certain distance. Therefore, movement of a mouse cord is prevented from being obstructed by the control member, so a mouse can move smoothly, and smooth operations of the mouse are ensured.
