1. A method of producing a functional roll comprising a rotation shaft and a roll body comprising nonwoven fabric sheets provided on the rotation shaft, including the following steps:
stacking multiple nonwoven fabric sheets shaped into a circular form with an opening in the center while a mounting shaft is inserted in the opening; clamping a nonwoven fabric sheet group comprising the multiple stacked nonwoven fabric sheets with a set of a first jig and a second jig, and compressing the nonwoven fabric sheet group in the direction parallel to the mounting shaft via the jigs; securing the set of jigs to each other to unite the nonwoven fabric sheets forming the nonwoven fabric sheet group; heating the united nonwoven fabric sheet group so that the nonwoven fabric sheets forming the nonwoven fabric sheet group adhere to each other; and removing the mounting shaft and jigs from the nonwoven fabric sheets adhering to each other to create a module comprising the nonwoven fabric sheets adhering to each other.
