PROBLEM TO BE SOLVED: To highly precisely authenticate a fingerprint even when the size of mounted keys become smaller due to downsizing of the mobile wireless unit such as a mobile phone. SOLUTION: The mobile wireless unit is provided with keys having a fingerprint sensor function and entering an instruction different depending on a depressed key, a memory that registers the fingerprint sensed by the fingerprint sensor, a fingerprint matching section that matchs the fingerprint having been registered in the memory with the fingerprint sensed by the fingerprint sensor, and a changeover section that switches the wireless unit to be able to enter an instruction from the key when they are matched with each other. |
