The device comprises an imaging device for imaging blood vessels of a hand of the user in a noncontact way including a position/direction/shape instructing means for instructing the user to hold up a user's hand, one or more irradiating means for irradiating the hand with near infrared radiation, and one or more imaging means for producing an image by the near infrared radiation; a blood-vessel image extracting the blood-vessel image from the produced image; a blood-vessel image storage means for storing the hand blood-vessel image of each user; and an identifying means for identifying the user by comparing the extracted blood-vessel image with the stored blood-vessel image.
