PROBLEM TO BE SOLVED: To provide a technology which can improve cutting precision of a membrane member.SOLUTION: A cutting device 100 cuts a laminate membrane member LB including an electrolyte membrane 1 for a fuel battery and a gas diffusion layer 7. The cutting device 100 includes a pressing part 112 which holds a non-cut portion except for a cut portion of the laminate membrane member LB, and a suction table 124. The cutting device 100 includes a punch part 111 which punches the cut portion of the laminate membrane member LB. The punch part 111 separates the cut portion by separating from the non-cut portion of the laminate membrane member LB held by the pressing part 112 and the suction table 124 in a state that the cut portion of the laminate membrane member LB is sandwiched together with a receiving part 122. |
