An IC card provided with an IC chip, and configured to enable at least one of contact communication and contactless communication, the IC chip comprising:
- an ultrasonic fingerprint sensor connected to the IC chip;
- and
- a storage unit in which fingerprint data for matching is stored;
- wherein
- an outer surface of the IC card is formed of synthetic resin, and
- the ultrasonic fingerprint sensor is covered with the synthetic resin, wherein
- the IC card comprises:
- a flexible substrate comprising a polyimide base material;
- a conductor layer on the flexible substrate, the IC chip, the storage unit and the fingerprint sensor are patterned in said conductor layer;
- a resin frame on the flexible substrate, the resin frame having an opening that exposes the IC chip, the storage unit and the fingerprint sensor;
- and
- a cured resin layer in the opening of the resin frame, the cured resin layer sealing the IC chip, the storage unit and the fingerprint sensor.
