A composite sheet manufacturing device for compounding strips produced from a first sheet and a second sheet, the first sheet having an adhesive surface, the device comprising: a cutter roller configured to rotate about a predetermined axis and including a main body and a cutter mounted thereon and shaft portions respectively extending outward from opposite end surfaces of the main body in a rotary shaft direction of the cutter roller; an anvil roller configured to cut the first sheet into strips by introducing the first sheet to between the cutter roller and the anvil roller by rotating relative to the cutter roller; and a cooling unit configured to cool at least one of the anvil roller and the cutter of the cutter roller by a refrigerant, the cooling unit including: a cutter-roller side refrigerant flowing part formed in the cutter roller and configured such that the refrigerant flows inside; a cutter-roller side center hole formed inside the main body of the cutter roller and extending in a rotary shaft direction of the cutter roller; a cutter-roller side refrigerant introducing pipe extending along an axial direction of the cutter-roller side center hole in the cutter-roller side center hole with a clearance defined between an inner peripheral surface of the cutter-roller side center hole and the cutter-roller side refrigerant introducing pipe and having a tip arranged in the cutter-roller side center hole to introduce the refrigerant into the cutter-roller side center hole; and a cutter-roller side packing configured to seal between an outer peripheral surface of the tip of the cutter-roller side refrigerant introducing pipe and the inner peripheral surface of the cutter-roller side center hole, wherein the cutter-roller side refrigerant flowing part includes an entrance for introducing the refrigerant into the cutter-roller side refrigerant flowing part from outside and an exit for discharging the refrigerant to the outside of the cutter-roller side refrigerant flowing part; and the entrance of the cutter-roller side refrigerant flowing part communicates with the cutter-roller side center hole at a position closer to the tip of the cutter-roller side refrigerant introducing pipe than the cutter-roller side packing and the exit of the cutter-roller side refrigerant flowing part communicates with the cutter-roller side center hole at a position closer to a base end of the cutter-roller side refrigerant introducing pipe than the cutter-roller side packing.
