Disclosed in the present invention are a fingerprint recognition device and a mobile terminal. The fingerprint recognition device comprises a dielectric cover plate, a support with a through hole, a sensing chip, a control circuit and a bottom plate; the dielectric cover plate is accommodated in the through hole and is tightly connected with the sensing chip, the sensing chip collects fingerprints by pressing the dielectric cover plate with fingers and generates an analog signal, the control circuit processes the analog signal and recognizes the fingerprints; the sensing chip comprises a sensing part and a connecting part formed by radically extending from the edge of the sensing part, the sensing part is connected with the dielectric cover plate, and the connecting part is electrically connected with the bottom plate. Since the connecting part is kept away from the dielectric cover plate, the location of bonding wires can be avoided only either by machining a groove or a gap on the support, or by arranging a lug boss on the dielectric cover plate to present a stepped shape, which ultimately averts the situation in which the location of bonding wires is avoided by machining a groove on the sensing chip; hence, both the difficulty in machining and the production cost are reduced. |
