Optical fingerprint image capturing device

The utility model provides an optical fingerprint image capturing device. The optical fingerprint image capturing device comprises a substrate, a photosensitive module, at least one light-emitting element, a hollow shell and a light-transmitting pressing plate, the substrate extends along a reference plane. The photosensitive module is disposed on the substrate. The at least one light-emitting element is disposed on the substrate. The hollow housing is disposed on the substrate to surround the photosensitive module and the at least one light emitting element. The hollow shell comprises an outer wall part and a first embedding part which extends inwards from the outer wall part in the direction parallel to the reference plane. The first embedding part comprises a first embedding surface; the light-transmitting pressing plate is arranged on the first embedding face, the outer wall portion of the hollow shell surrounds the light-transmitting pressing plate and the substrate, the first embedding portion surrounds
