SUBJECT of the Invention A paper manufacturing process， especially the papermaking process WHEREIN: When adding a chemical|medical solution to a process water type|system|group， rapid and uniform mixing by an aqueous|water system and dispersion|distribution are enabled， and the diluted addition method of the chemical|medical solution which can reduce a favorable paper product characteristic and chemical|medical solution addition amount is provided. PROBLEM to be solved In order to solve the said subject， in a paper manufacturing process， the underwater stirring apparatus installed in the reservoir water of a water retention part is utilized， A negative pressure is generated in the underwater stirring apparatus because the underwater stirring apparatus injects the jet water-flow water in which the chemical|medical solution was added， Reservoir water is sucked in to the underwater stirring apparatus with the negative pressure， and a chemical|medical solution is disperse|distributed by discharging the diluted chemical|medical solution made by mixing jet water-flow water and reservoir water in the reservoir water of the water retention part in which the underwater stirring apparatus was installed， The above-mentioned was set as the structure of the diluted addition method of a chemical|medical solution by which it is characterized.
