The present invention provides a
dilution-type
disinfectant solution generating device and dental
treatment system that are simple in configuration and capable of diluting
disinfectant solutions to desired concentrations. [Solution] The diluted
disinfectant solution generating device 1 includes a
stock solution tank 30 capable of storing disinfectant solution L1,
dilution solution tanks 10 and 20 capable of storing diluted disinfectant solution L2 obtained by diluting the disinfectant solution L1 supplied from the
stock solution tank 30 with water to a desired concentration, and transport pipes 2, 2a, 2b, 2c, and 2d that can take out the diluted disinfectant solution L2 from the
dilution solution tanks 10 and 20 and distribute it.
