A luminous mouse pad includes a base plate, a light source, and a light-guiding pipe. The light source is disposed in the fixing unit. The light-guiding pipe is fixed on a periphery of the base plate. At least one end of the light-guiding pipe is adjacent to the light source and guides a light from the light source into the light-guiding pipe. The light-guiding pipe is exposed outside the periphery of the base plate, so that the light from the light source irradiates from a surface of the light-guiding pipe.
