PROBLEM TO BE SOLVED: To provide a suction and discharging apparatus for minute amount of liquid enabling automatic suction and discharging of the minute amount of the liquid and exact handling of desired amount thereof and further blowing the sucked liquid securely. SOLUTION: The suction and discharging apparatus comprises a common flow path (10), a solenoid valve (1) connected to a tip of the common flow path (10) with a supply port (20), an electrically controlling part(2) to control opening/closing of the solenoid valve (1) with time, a positive pressure generating means (3) and a negative pressure generating means (4) which are arranged at a base end of the common flow path (10), and a switching means (5) for switching between positive pressure/negative pressure of the supply port (20) of the solenoid valve (1). The suction and discharging apparatus is constituted to suck the liquid from the tip of the solenoid valve (1) in a negative pressure open state of the solenoid valve (1) and to discharge the liquid sucked from the tip of the solenoid valve (1) in a positive pressure open state of the solenoid valve (1).
