    • PROBLEM TO BE SOLVED: To provide an inexpensive small-sized liquid control device capable of sending, mixing and agitating liquid existing in a channel in a micro-fluid device by a two-phase oscillation signal, and localizing a sample in the liquid. SOLUTION: This liquid control device for controlling the liquid existing in the channel in the micro-fluid device has the micro-fluid device having the liquid in the channel; a control means for generating information for controlling each process for stopping, sending, mixing and agitation of the liquid in the micro-fluid device, and localization of the sample in the liquid; a signal generation part for generating a voltage signal corresponding to information from the control means; an ultrasonic vibrator oscillated by the voltage signal from the signal generation part; and a holding part for holding the ultrasonic vibrator to face to a part of the channel in the micro-fluid device. In the liquid control device, each process is performed by transmitting oscillation of the ultrasonic vibrator to the liquid existing in the channel through the holding part.
