PROBLEM TO BE SOLVED: To provide a monitor capable of monitoring the heating state of a resin inside a heating cylinder of an injection molding machine highly precisely by reducing errors when obtaining a temperature difference by using a thermocouple, and obtaining heat flow flux more precisely. SOLUTION: The at least two thermocouples A-1, A-2 are respectively arranged in different positions. A controller 130 has a signal processing section 301 which determines the heat flow flux between the different positions based on the voltages detected by the thermocouples. Either of the respective positive poles and negative poles of the thermocouples A-1, A-2 is connected to the signal processing section 301 and another side is mutually connected. The signal processing section 301 determines the heat flow flux between the different positions based on the voltage between one of the positive pole and the negative pole.
