PURPOSE:To provide a culture solution conveyer capable of continuously conveying cell bodies in the culture solution together with the culture solution without damaging the cell bodies. CONSTITUTION:This culture solution conveyer involves two or more receiving tanks 1 and 6 arranged parallel to each other for temporarily storing a cell body-containing culture solution sent from a culture tank, liquid level sensors 5 for detecting the level of the culture solution in the receiving tanks, a conveying pipe 11 for conveying the culture solution from the culture tank to the receiving tanks, a discharge pipe 13 for discharging the culture solution from the receiving tank, a force feed gas inlet pipe 12 for introducing a force feed gas to the receiving tanks, gas discharge pipes 22 and 23 for discharging gas from the receiving tanks, a pressure sensor 16 for the force feed gas and control valves 3 and 8 respectively attached to the conveying pipe, the discharge pipe, the force feed gas inlet pipe and the gas discharge pipes. This conveyer involves also a controller 15 for controlling opening and closing of the respective control valves and the pressure of the force feed gas so as to continuously discharge the culture solution by repeatedly storing and discharging the culture solution into and from the respective receiving tanks in order based on signals sent from the liquid level sensors and the pressure sensor.
