Thus, fingerprint sensor assembly 20 can have fingerprint identification function, and response element 30 does not have response limiting function, but has the effect that response user finger presses down press section, and user is pointed can have pressing touch.
Wherein, fingerprint sensor assembly 20 is located at the position pointed closer to user than response element 30.Such as, response element 30 can be located at the below of fingerprint sensor assembly 20.Thus, fingerprint sensor assembly 20 distance users finger is nearer, and the fingerprint of fingerprint sensor assembly 20 pairs of user's fingers of being more convenient for identifies, identity is good.
