Mouse pad

A mouse pad, comprising:

• a full flat contact surface arranged on one side surface of the mouse pad, wherein the full flat contact surface is configured to allow a mouse to move to any position thereof;
• a contact plate, one side surface of the contact plate defining an entirety of the full flat contact surface;
• a light guide body having two opposite side surfaces that are respectively defined as a first top surface and a first bottom surface, wherein the contact plate is disposed on the first top surface, and the light guide body has a plurality of light guide holes;
• a base disposed on the first bottom surface of the light guide body, wherein the light guide body is located between the contact plate and the base;
• and
• a light emitting module including:
• a circuit board disposed on the first bottom surface of the light guide body, wherein the circuit board is located between the light guide body and the base;
• and
• a plurality of light emitting units disposed on the circuit board, wherein the plurality of light emitting units are respectively located in the plurality of light guide holes, light beams emitted from the plurality of light emitting units are emitted outward from an edge of the light guide body by being guided through the light guide body, and a second top surface of each of the light emitting units is shielded by the contact plate;
• wherein the light guide body has a light-shielding member receiving groove recessed in the first top surface thereof, the light-shielding member is disposed in the light-shielding member receiving groove, and a depth of the light-shielding member receiving groove is not less than a thickness of the light-shielding member, and wherein an outer surface of the light-shielding member and the first top surface of the light guide body jointly define a first flat surface, and the contact plate is disposed on the first flat surface.
