Abstract
The biometric information input apparatus comprises a fingerprint sensor which detects biometric information, and moisture absorbing units and which are arranged adjacent to the fingerprint sensor and absorb moisture. The moisture absorbing units and have a groove structure which generates a capillary phenomenon. The fingerprint sensor is of the sweep type which scans biometric information through relative displacement with the finger, and is formed in parallel with the direction of relative displacement between the groove structure and the finger. The groove structure has a width smaller than the pitch of the ridges of an average fingerprint.
