PURPOSE: The hand-held counterfeit-bill detecting apparatus and hand-held counterfeit-bill sensor using the same accurately can decide the truth of the confirmation object paper currency. CONSTITUTION: The electro magnetic wave sensor unit(301) emits the electro magnetic wave. The reflective signal reflected to the confirmation object paper currency is a message received. It amplifies the received reflective signal and the signal amplification part(302) filters. Comparing the reflective signal which the electro magnetic wave signal processing unit(303) is amplified with the saved normality paper currency reflecting value.
