Abstract: A combined roll is a roll of a wound strip that includes a plurality of layered bodies each including a polymer electrolyte membrane and a pair of electrode catalyst layers, and a supporting member including a plurality of frame units arranged in a single direction, with each frame unit supporting one layered body. The frame unit surrounds the electrode catalyst layers and is in contact with the electrode catalyst layers, with the outer periphery of the polymer electrolyte membrane held inside the frame unit in the thickness direction.
