PROBLEM TO BE SOLVED: To provide a chemical-solution feeder which can appropriately maintain the concentration of a chemical solution supplied from a chemical-solution container. SOLUTION: The chemical-solution feeder for liquid flowing intermittently is provided with a support 2, a guide member 5, a supply part 4, and an adjustment mechanism. The support 2 supports the chemical-solution container 1, and the guide member 5 guides the chemical solution to the position where it is brought into contact with the liquid. Then the supply part 4 supplies the chemical solution to the guide member 5, and the adjustment mechanism retains and discharges the chemical solution in a shock absorption chamber 6 in accordance with temperature fluctuations. Then the shock absorption chamber 6 is provided with a lower member 20 and a top member 31. The lower member 20 is provided to the support, and the top member 31 is engaged with the lower member from above. Then the lower member 20 of the chemical-solution feeder is provided with a bottom wall and an outer wall 23 extended upward from the bottom wall, and the top member 31 is provided with a top wall 34 and an inner wall 33. The top wall 34 covers the top of the shock absorption chamber 6, and the inner wall 33 hanging down from the top wall is enaged with the inside of the outer wall 23. COPYRIGHT: (C)2007,JPO&INPIT
