PROBLEM TO BE SOLVED: To provide a cell stack of an electrolyte circulation type battery surely preventing contact of a terminal electrode being connected to the cell stack to an electrolyte and preventing loss of input/output function of electric power. SOLUTION: The cell stack 1 is formed by stacking a plurality of cells each comprising a positive electrode 3, a separator 4, and a negative electrode 5 arranged between bipolar plates 21, and has a plate-shaped terminal electrode 6 connected to a positive electrode 3 or a negative electrode 5 and inputting or outputting electricity. A terminal electrode protection part 10 is formed by covering the whole part excluding a part being drawn out to the outside of the cell stack in the terminal electrode 6. A fixing member 7 covering the outer circumferential edge part and one surface through the terminal electrode protection part 10 and fixing the terminal electrode 6 is installed. The terminal electrode 6 is connected to the positive electrode or the negative electrode through the terminal electrode protection part 10. The outer circumferential edge part on the surface on the connection side with the positive/negative electrodes of the terminal electrode protection part 10 is bonded to the fixing member 7.
