PROBLEM TO BE SOLVED: To provide a water quality inspection device capable of automatically and continuously detecting a change in the concentration of an ion contained in flowing water. ! SOLUTION: A water quality inspection device 1 is constituted of reverse osmosis membrane means 3 disposed in a branch route 2 for inspection branched from a supply route and ion inspection means 4 for detecting a contained ion. The ion inspection means 4 is constituted of: a light-emitting part 43 for emitting white light; and a color sensor part 44 for detecting the color component of the contained ion using the light which has been emitted from the light-emitting part 43 and which flowing water and concentrated water has transmitted; and a display part 46 for displaying the color component detected by the color sensor part 44. The light-emitting part 43 emits white light into the concentrated water via a first transmission window of a flowing water route 41 of the concentrated water. The color sensor part 44 receives |
