An object of the invention is to precisely guide the position of an eye in order to acquire an excellent eye image which is suitable for an authentication. The invention provides an eye image pick-up apparatus including an image pick-up unit for picking up an image of an object, a mirror (40) provided on a front face of the image pick-up unit perpendicularly to an optical axis of the image pick-up unit and serving to reflect a reflected image of the object, an opening section (42) provided in a portion of the mirror (40) which intersects the optical axis and serving to align a position of an eye in the reflected image of the object reflected in the mirror (40), visible light source sections (46) and (47) provided on both left and right ends at a back side of the mirror (40), and shielding plates (43) and (44) provided on both left and right ends at a front side of the mirror (40) and serving to shield a light emitted from the left and right corresponding visible light source sections (46) and (47). A person to be authenticated can easily decide whether his (her) own left or right eye is held in a photographing position depending on whether the visible light source sections (46) and (47) on back faces can be seen from the left and right shielding plates (43) and (44).
