PROBLEM TO BE SOLVED: To provide an immersion cell which has high operation reliability achieved by preventing unexpected destruction of an ampule due to a sideways shock, and improved fuel cell performance achieved by making electrolyte solution flow in power generating elements quickly and certainly. SOLUTION: The immersion cell comprises: a laminate 5 constituted of a fastening plate 3, a spacer 4, and the power generating elements 2 sandwiched between the fastening plate 3 and the spacer 4, which has a cavity 6 in its central region; an ampule 7 in which the electrolyte solution 8 is encapsulated; and a cell case 1 in which the laminate 5 and the ampule 7 disposed in the cavity 6 of the laminate 5 are contained. Synthetic resins 14 and 15 are formed on tapered surfaces 14a and 15a at least with inner peripheral surfaces facing the cavity 6 and extending towards inner diameters the power generating elements 2, and disposed on inner peripheral surfaces of the fastening plate 3 and the spacer 4.
