摘要： There is provided a die plate, a resin machine, and a method of heating nozzles of the die plate that can suppress temperature unevenness of the nozzles and increase the temperature rise performance of the nozzles. The die plate includes a nozzle group including a plurality of nozzles through which molten resin passes, and a heating medium guidance part that guides a heating medium for heating a nozzle wall of each nozzle. The heating medium guidance part includes an inlet that receives the heating medium, an outlet that discharges the heating medium from a heating medium channel, and a guidance wall that defines a heating channel that causes the inlet and the outlet to be in communication with each other together with an outer peripheral surface of the nozzle wall of each of the plurality of nozzles.
