PROBLEM TO BE SOLVED: To provide a reserve tank capable of reducing an alteration range of a forming die when a capacity of an air chamber is adjusted. SOLUTION: In the reserve tank provided with a tank body 2 constituting a space for absorbing the variation of an amount of cooling water in a cooling circuit and communicated with the inside of the cooling circuit, partition walls 41-43 for dividing the space to a plurality of chambers 5a-5f are formed on the tank body 2 and ceiling surfaces 21a-21f are formed in the plurality of chambers 5a-5f at an upper side in a vertical direction, respectively. The ceiling surfaces 21a, 21b in the chambers 5a, 5b of parts of the plurality of chambers 5a-5f are arranged at a lower side in a vertical direction of the ceiling surfaces 21c-21f in the other chambers 5c-5f. A portion at an upper side in the vertical direction of the ceiling surface 21a, 21b of the chambers 5a, 5b of parts on the partition wall 41 for partitioning the chambers 5a, 5b of parts and the chambers 5c, 5d adjacent to the chambers 5a, 5b of parts formed at the outer wall of the tank body 2.
