Abstract:

To provide a micro-pump and an operation method for the micro-pump for simply controlling a flow rate.

In the micro-pump equipped with the heating element, substantial pulsed operation of the heating element is performed by a control device. In the heating element, a heating phase (T2) and a stationary phase (T1) are alternated with each other, and an accurate control of the flow rate is performed on the basis of the pulsed operation.
