Abstract

According to one embodiment, a processing liquid generator capable of improving the reliability of the concentration of generated processing liquid is provided. A processing liquid generator that generates processing liquid having undergone concentration adjustment includes a processing liquid adjuster (), which adjusts the concentration of the processing liquid, a first processing liquid path P, through which the processing liquid flows to the processing liquid adjuster (), a second processing liquid path P, through which the processing liquid flows to the processing liquid adjuster, a first concentration meter, which measures the concentration of the processing liquid flowing through the first processing liquid path P, the measured concentration being the concentration of a component involved in the concentration adjustment in the processing liquid adjuster (), a second concentration meter, which measures the concentration of the processing liquid flowing through the second processing liquid path P, the measured concentration being the concentration of a component that is involved in the concentration adjustment and should be measured with the first concentration meterin terms of concentration, a first valve mechanism, which opens and closes the first processing liquid path P, and a second valve mechanism, which opens and closes the second processing liquid path P
