In the chemical liquid management system for the substrate processing device, a piping provided with an accumulative flow meter connects the substrate processing device with a chemical liquid preparing device preparing new liquid of chemical liquid and a chemical liquid regenerator for regenerating the chemical liquid being used. A concentration management device measures the concentration of the chemical liquid of the substrate processing device, adding the stoste or the new liquid and regenerated liquid of the chemical liquid, managing the chemical liquid to be with the optimal concentration. The accumulative flow of the supplied added liquid is metered by the accumulative flow meter which is connected with a network directly.
