1. A mobile phase temperature control device for a supercritical fluid apparatus that is used in a supercritical fluid apparatus including a separation column to which a mobile phase in a supercritical state is supplied, comprising:
a rod-shaped cartridge heater that is provided at a position farther upstream than the separation column and preheats liquid carbon dioxide such that the liquid carbon dioxide in the mobile phase is put in a supercritical state in the separation column;
a flow path portion that is wound around the cartridge heater and guides the mobile phase to the separation column; and
a first temperature sensor that is attached to the flow path portion and detects a temperature of the flow path portion.
