Abstract: A chemical solution synthesis device comprises a chemical solution holding unit, a reaction vessel, a first chemical solution feed unit, a chemical solution feed and discharge unit, and a second chemical solution feed unit. The chemical solution holding unit is configured to hold a chemical solution. The chemical solution and carriers are reacted in the reaction vessel. The chemical solution is transferable from the chemical solution holding unit to the reaction vessel without coming into contact with atmosphere. The first chemical solution feed unit is connected to the reaction vessel and configured to supply the chemical solution to the reaction vessel. The chemical solution feed and discharge unit is provided vertically above the first chemical solution feed unit. The second chemical solution feed unit is configured to suppress adhesion of the carriers to the reaction vessel.
