A shell, a fingerprint module and a mobile terminal are provided. The shell comprises an outer cover plate and an inner cover plate, which are stacked vertically and bonded together. The outer cover plate faces towards users. The outer cover plate or the inner cover plate is provided with a through hole. The part, corresponding to the through hole of the outer cover plate, of the inner cover plate is used for jointing a fingerprint chip, or the through hole of the inner cover plate is for a fingerprint chip to pass through so the fingerprint chip can be jointed on the outer cover plate. The outer cover plate or the inner cover plate is provided with a through hole, so that the distance between the fingerprint chip and a user fingerprint at the through hole of the shell is reduced, and the fingerprint chip can collect fingerprint information easily. Moreover, the through hole only causes stress damage to the outer cover plate or the inner cover plate, the stress of the shell can be reinforced by use of the inner cover plate without no through hole or the outer cover plate without no through hole, and therefore, the production yield of the shell is increased.
