PROBLEM TO BE SOLVED: To provide a small solution purification device effectively demonstrating photocatalytic activity for a purifying object solution, with simple and small structure, particularly suited to sterilization of cut flower dipping liquid and decomposition of organic matter. SOLUTION: Non-woven fabric carrying a photocatalyst, titanium oxide in particular, or a metallic mesh type photocatalyst carrier and an ultraviolet light emitting diode are faced to be juxtaposed, a solution passage allowing the purifying object solution to flow is formed therebetween, and these are contained in one vessel to form the small solution purification device, particularly suited to sterilization of cut flower dipping liquid.
