PROBLEM TO BE SOLVED: To provide a power supply device of an electronic apparatus capable of detecting imperfect mounting of a battery pack with a simple structure without impairing miniaturization. SOLUTION: This power supply device of an electronic apparatus is so structured that, when a plunging amount of an electrode terminal of the battery pack is reduced to project a contact terminal part 9a of a connector piece 9 into a housing space of the battery pack by a predetermined amount in removing the battery pack from a holder, the connector piece 9 comes into contact with a contact member 10 to output a detection signal.
