A drug solution inspection device includes a jig that mounts thereon a syringe containing a drug solution, an imaging unit that captures an image of the syringe mounted on the jig, an exposure unit that performs exposure on the syringe mounted on the jig, and a first control unit that controls the imaging unit and the exposure unit to acquire inspection information. In order to inspect an amount of the drug solution in the syringe, the first control unit transmits the captured image of the syringe while changing an exposure state of the exposure unit.
