A basic manufacturing method of a resin roll includes a procedure in which a synthetic resin outer cylinder (1) molded in the shape of a cylinder is arranged so as to cover an outer surface of a metal core (2), a clearance formed between metal core (2) and outer cylinder 1 is filled with a thermoset adhesive (3), and adhesive (3) is hardened to integrate the constituents into one piece through bonding. The manufacturing method of a resin roll has a feature in that integration of the constituents into one piece through bonding is performed by first hardening of the adhesive in a state where outer cylinder (1) is held at a first temperature and adhesive (3) is thereafter heated at a second temperature higher than the first temperature for second hardening.
