Zusammenfassung:Provided are a fingerprint module and a mobile terminal in some embodiments of the present disclosure. The fingerprint module includes a fingerprint identification chip, a flexible circuit board, and a pressure detection unit. The pressure detection unit includes a rigid substrate and a pressure detection circuit formed on the rigid substrate. The fingerprint identification chip and the pressure detection unit are disposed on two opposite surfaces of the flexible circuit board respectively, and are separately electrically connected to the flexible circuit board respectively. In the embodiments of the disclosure, the pressure detection circuit is directly formed on the rigid substrate, and the rigid substrate with the pressure detection circuit replaces a reinforcing steel sheet and a flexible circuit board for manufacturing a pressure sensor in the existing art. Such design can not only achieve a pressure detection function, but also decrease an overall thickness of the fingerprint module and reduce an impact of the fingerprint module on the overall thickness of a device.
