description	A driving device of a micropump and a microvalve is provided. The driving device comprises a pump driver controlled by a pump controller, a valve driver controlled by a valve controller, a power supply part, a switch part. The pump driver having a first shape memory alloy wire, a micropump of the first shape memory alloy wire, a wiring part arranged in parallel to the first shape memory alloy wire, and a first selector switch that switches between a state where only the first shape memory alloy wire is energizable and a state where the wiring part is energizable. The valve driver having a plurality of second shape memory alloy wires, a plurality of microvalves of second shape memory alloy wires, and a second selector switch that brings into a state where one of the plurality of second shape memory alloy wires is energizable.
