PROBLEM TO BE SOLVED: To provide an agitating and storing vessel used for producing calcium polysulfide, with which deposition of a crystal on the inner wall surface of a vessel main body can be prevented. SOLUTION: In the agitating and storing vessel used for producing calcium polysulfide, in which an agitating blade (3) is turnably arranged at the inside of the vessel main body (2) so as to agitate an aqueous solution (stored solution (16)) of calcium polysulfide stored in the vessel main body (2), the agitating blade (3) has a blade body (10) which is attached to a rotary shaft (9) in such a manner that it can slide along the shaft line and which is ascended and descended by the action of buoyancy according to ascending and descending of the surface (17) of the stored solution(16).
