    摘要: Hot water (12) in a bath (11) is pumped up by a suction pump (9) and introduced into a carbon dioxide gas dissolver (7) through solution flow rate adjusting means (14) and then, poured into the bath (11). Carbon dioxide gas supplied from a carbon dioxide gas cylinder (1) is introduced into the carbon dioxide gas dissolver (7) through gas flow rate adjusting means (5). At this time, the quantity of bubbles existing in artificial carbonated spring in a take-out pipe (15) is measured with a measuring device (13), and the solution flow rate adjusting means (14), gas flow rate adjusting means (5) and the like are controlled by means of a control device (16) using a relational expression between a preliminarily set quantity of bubbles and carbon dioxide concentration to obtain a desired concentration of carbon dioxide gas in carbonated spring. Because the carbon dioxide gas flow control means (5) is provided between the carbon dioxide gas dissolver (7) and a carbon dioxide gas supply source, carbonated spring of a high concentration can be always manufactured even if the pressure of supplied carbon dioxide gas changes or the permeating performance of a membrane changes.
