Provided is an electronic device which can reduce possibility of generation of a secondary damage on an electronic circuit caused by a shock. A mobile telephone includes a case, an electronic circuit block mounted on the case, an acceleration sensor which measures an acceleration of the case, and a CPU. The CPU has a detection unit which detects a level of a shock applied to the case according to the acceleration value measured by the acceleration sensor and a control unit which limits electric communication to the electronic circuit block according to the detected shock level.
