Dilute chemical solution production device has a plunger pump and a chemical solution supply pipe that supply a chemical solution from a chemical solution reservoir. The end of the chemical solution supply pipe serves as an injection point for the chemical solution. The chemical solution supply pipe is inserted to an approximately central position in the radial direction of an ultrapure water passage, which is a first pipe, via a bore-through joint. Conductivity meter as a conductivity measuring means is provided on the downstream side of the bore-through joint, which serves as the injection point, and is connected to the previously described control means so that the plunger pump can be controlled in accordance with the measured value of the conductivity meter. The dilute chemical solution production device is capable of producing, with a simple structure, a dilute chemical solution having an extremely low concentration of acid/alkali or the like.
