A driver abnormality sign detection device includes a control circuit configured to detect an abnormality sign of a driver based on visual line information and on information for calculating a visual line parameter influencing motion of a visual line of the driver. The control circuit acquires a predetermined reference feature amount representing the motion of the visual line, calculates the visual line parameter, calculates a predicted feature amount representing the motion of the visual line by correcting the reference feature amount with a correction value acquired based on the visual line parameter, calculates a visual line abnormality degree which represents an extent that a measured feature amount acquired based on the visual line information and representing the motion of the visual line diverges from the predicted feature amount, and detects, based on the visual line abnormality degree, presence or absence the abnormality sign of the driver.
