BIOMETRIC INFORMATION IMAGE-CAPTURING DEVICE, BIOMETRIC AUTHENTICATION APPARATUS AND MANUFACTURING METHOD OF BIOMETRIC INFORMATION IMAGE-CAPTURING DEVICE

摘要

A biometric information image-capturing device includes an image capturing unit configured to photograph a body part including biometric information to generate a biometric image in which the biometric information is represented, at least one light source disposed in the periphery of the image capturing unit and configured to illuminate light toward a photographing range of the image capturing unit, and a light guide member disposed to be opposed to the at least one light source in the periphery of the image capturing unit and provided with a concaved portion located at a surface of the light guide member, the concaved portion being nearer to the image capturing unit side than the at least one light source.
