A method for manufacturing a concrete structure comprises an installation step of installing a formworkfor concrete placement, a placement step of performing concrete placement in a state where a curing sheetis attached to an inner surface of the formwork, and a demolding step of removing the formworkafter placement of concrete C. A contact angle of a contact surface of the curing sheetfor use in the placement step with water is 50 degrees or more, wherein the contact surface faces the concrete. Thus, generation of bleeding water is suppressed.
