PROBLEM TO BE SOLVED: To provide a liquid chromatograph device capable of keeping a heat quantity generated from a light source in a constant state even if a room temperature is fluctuated, and suppressing fluctuation of a base line of a detection signal. SOLUTION: The device includes: a fan provided on a detector for detecting a sample component, for sending air to a light source unit for irradiating the component with light; a temperature sensor for measuring the temperature of the air; a heat exchanger for exchanging heat with the air; and a control unit for controlling the heat exchanging amount exchanged with the air by the heat exchanger based on a rotational frequency of the fan and the temperature of the air measured by the temperature sensor.
