A keyboard with liquid-draining function, at least including: keys, elastic body layer, circuit board layer, bottom board and sealing layer; wherein the bottom board is installed with at least a liquid-draining hole, with the dividing mechanism being installed between the circuit board layer and the bottom board to form a liquid-draining space. The liquid-draining space and the liquid-draining hole are connected for the purpose of draining liquid that is accidentally poured into the keyboard, so that liquid flowing down through the keys can be drained away swiftly via the liquid-draining space and drained out of the keyboard through the liquid-draining hole, thus preventing liquid from accumulating in the keyboard, and maintaining the normal operation of the keyboard.
