A mouse device includes a main body and at least one mouse foot pad. The mouse foot pad is fixed on the lower surface of the main body. The mouse foot pad includes a first layer with first friction coefficient μand a second layer with a second friction coefficient μ, where the second friction coefficient μis greater than the first friction coefficient μ. The first layer and the second layer are formed as a laminate. The second layer is bonded to the lower surface of the main body. The first layer is in contact with the working plane when the mouse device is operated. When the second layer is in contact with the working plane, the user is reminded that the mouse foot pad needs to be changed.
