Abstract: This application provides a capacitive fingerprint recognition module, including a substrate, a fingerprint recognition chip, a mold compound, a chip adhesive layer, and a cover plate. The mold compound and the fingerprint recognition chip are disposed on the substrate, and the mold compound packages the fingerprint recognition chip. The cover plate is covered on the chip adhesive layer, so that a squeezed part of the chip adhesive layer is squeezed beyond an edge of the cover plate and is exposed outside. The chip adhesive layer is selected from a non-white material, and therefore the squeezed part of the chip adhesive layer is visually hidden. By means of the configuration, a process of clearing the squeezed part of the chip adhesive layer may be omitted.
