There is provided a device which detects sleepiness of a human being based on the opening and closing motion of an eyelid, in which an occurrence of sleepiness of a subject is detectable with accuracy more sufficient than before even for a subject who keeps from blinking intentionally when sleepiness increases. The inventive sleepiness detecting device comprises a means for detecting an opened/closed state of an eyelid of a subject; a means for detecting sequentially a time interval between transitions between an opened state and a closed state of the eyelid; a means for computing an eyelid opening/closing characteristic amount from time series data of the time intervals; a sleepiness judging means for judging that the subject feels sleepiness when the eyelid opening/closing characteristic value falls below a first threshold value or exceeds beyond a second threshold value higher than the first threshold value.
