PROBLEM TO BE SOLVED: To provide a door opening/closing device which servs as a door that hides the control button of an electronic apparatus and a door that opens or closes automatically when it is moved a little, and kept high in both controllability and state stability. SOLUTION: The door opening/closing device is equipped with a cam fixed to a door, and the door is kept open or close by a spring force. A force required for enabling the closed door to pivot for opening is set larger than the other force required for enabling the opened door to pivot for closing. Furthermore, the cam is composed of an elastic hook unit 1 and a stationary unit 2, and the rotating shaft 3 of the door is held in a space pinched between the hook unit 1 and the stationary unit 2.
