Fingerprint detector with a fingerprint sensor and fingerprint sensor mounting structure and fingerprint sensor

摘要

PROBLEM TO BE SOLVED: To provide a fingerprint sensor which can be applied to a portable information terminal or the like, which is small and lightweight and which can be mounted at high density, to provide a mounting structure for the fingerprint sensor and to provide a fingerprint detector equipped with the fingerprint sensor. SOLUTION: In the fingerprint sensor 1 which is provided with a sensor face 2 formed on a main face, a connecting electrode formed on the back and through electrodes 3 used to connect the sensor face to the connecting electrodes, the sensor face 2 is used as the surface, the connecting electrode installed on the back of the fingerprint sensor and electrodes on an external connecting board 5 are electrically connected via solder or the like. By this constitution, as compared with a conventional mounting structure using a bonding wire, the outer shape of the fingerprint detector can be formed in a size a little larger than the fingerprint sensor 1, and the fingerprint sensor can be mounted at high density.
