1. A biometrics authentication device, which verifies registered biometrics characteristic data for a user against biometrics characteristic data detected from a body to perform individual authentication, comprising: an image capture unit, which captures an image of a hand; a storage unit, which stores said biometrics characteristic data of the hand and body image capture state data which indicate a position of the hand for the user; a display unit, which displays guidance screens to the user for use in image capture of the hand; and a processing unit, which extracts the body image capture state data and biometrics characteristic data which indicate the position of the hand from the images of the hand captured by the image capture unit and registers the extracted body image capture state data and biometrics characteristic data in the storage unit, wherein the processing unit displays on the display unit, as the registered body image capture state data of the hand, an outline of the captured image of the hand, extracts the body image capture state data from images of the hand captured by the image capture unit, compares the extracted body image capture state data of the hand with the body image capture state data registered for the user, displays a guidance screen which indicates a guide direction of the hand according to the comparison result on the display unit, and verifies the biometrics characteristic data registered for the user against the biometrics characteristic data detected from the body.
