13. A fingerprint sensor configured to detect a fingerprint from at least two directions, the fingerprint sensor comprising:
a first fingerprint sensor provided on a front surface of a circuit board and configured to detect a fingerprint on the front surface; and
a second fingerprint sensor provided on a rear surface of the circuit board that is opposite to the front surface, and configured to detect a fingerprint on the rear surface,
wherein the first fingerprint sensor and the second fingerprint sensor are provided in a foldable electronic device of which at least a part is foldable, and
wherein at least one of the first fingerprint sensor and the second fingerprint sensor are further configured to detect the fingerprint based on light received through at least a part of the foldable electronic device from the at least two directions.
