PROBLEM TO BE SOLVED: To provide a chemical liquid agitator which has a simple structure and is capable of efficiently, automatically and uniformly agitating the whole of a chemical liquid without requiring any complicated operation such as liquid level monitoring or manual flow-passage switching, and also without causing bubbling or the like, irrespective of the level height of the chemical liquid in a chemical liquid tank. SOLUTION: This agitator is provided with: a chemical liquid introduction flow passage 11 for introducing a chemical liquid M pressurized with an external pump or the like, into a chemical liquid tank 5; an upper branch flow passage 12 which is branched from the chemical liquid introduction flow passage 11 as a branch and is used for introducing the chemical liquid M into the chemical liquid tank 5 at a comparatively higher position inside the tank 5; a lower branch flow passage 13 which is branched from the chemical liquid introduction flow passage 11 and is used for introducing the chemical liquid M into the chemical liquid tank 5 at a comparatively lower position inside the tank 5; and a flow rate adjustment means which consists of a three-way cock 30, a link mechanism 40 and a float 50 and is placed in the upper branch flow passage 12 and/or the lower branch flow passage 13 and used for automatically controlling the flow rate of the chemical liquid M flowing through the upper branch flow passage 12 and/or the lower branch flow passage 13 correspondingly to the level H of the chemical liquid M in the chemical liquid tank 5.
