Provided is a bonded sheet in which gas bubble retention can be limited, and a sheet member-bonding method with which gas bubble retention can be limited. The bonded sheet (70), which is used in a MEA (20), comprises gaskets (40, 60), which are first sheet members (71), and an electrolyte membrane (21), which is a second sheet member (72) that is laminated on the gaskets. The gaskets comprise first bonding sections (81) wherein at least a portion of grooves (83) provided in the plane of the sheet meet the sheet edge (73, 74), and second bonding sections (82) that do not have grooves. The electrolyte membrane is laminated on the gaskets in the first bonding sections and the second bonding sections. |
