Disclosed herein is a biometric authentication device. The biometric authentication device according to the present invention is configured such that it blocks visible light using an authentication button, the inside of which is opened or closed by a finger so as to realize the small size and slim shape of a biometric authentication device, and blocks infrared light or allows infrared light to pass while a driving unit moves vertically or horizontally by the operation of the authentication button. Accordingly, in the biometric authentication device, a camera module captures a normal image in normal mode, and captures an infrared pattern reflected from a finger in a vein authentication mode to perform biometric authentication.
