PROBLEM TO BE SOLVED: To provide a calibration device for a hydrogen gas sensor capable of adjusting easily hydrogen gas used for calibrating the rod-shaped hydrogen gas sensor having a gas detection part on the tip, and calibrating the hydrogen gas sensor safely and simply by using hydrogen gas. SOLUTION: In this calibration device 1 for the hydrogen gas sensor wherein a hydrogen gas generation agent is brought into contact with liquid in a sealed container 2, and a gas detection part is exposed to a hydrogen gas layer formed over the liquid, the sealed container 2 is equipped with a liquid discharge pipe 3 for adjusting a pressure of generated hydrogen gas to an atmospheric pressure, and a gas detection part insertion means 4 for inserting the gas detection part into the hydrogen gas layer in the air-uncontaminated state and exposing it thereto.
