A mouse pad of the present invention includes a first layer, a second layer and a plurality of flexible supporting fibers. The first layer is parallel to the second layer, and the supporting fibers are located between the first and second layers to separate the two layers apart. Thereby, a receiving room is defined between the first and second layers. The first layer is formed with a plurality of macroscopic micro bores which communicate with the receiving room. As such, situations such as dust accumulation on the bottom of a mouse can be mitigated.
