PROBLEM TO BE SOLVED: To provide an evaporating concentrator of a solution enabling the concentration and reuse of even a solution which causes decomposition of a component at elevated temperature and cannot be reused by deposition. SOLUTION: The evaporating concentrator of the solution comprises an air current circulation path closed to the outside and circulating an air current inside, air current circulation means for circulating the air current in the air current circulation path, also water content evaporation means for bringing a solution required for concentration treatment into contact with the air current, evaporating a water content in the solution and recovering the concentrated solution in the air current circulation path, solution mist separation means for separating a solution mist in the air current containing steam from the water content evaporation means from the air current, cooling means for cooling the air current containing the steam from which the solution mist from the mist separation means is separated, liquefying the steam and removing it, and water content mist separation means for separating a water content mist in the cooled air current from the cooling means from the air current and recovering it, in this order.
