To provide a door opening/closing device facilitating opening or closing motion of a door from the inside of a vehicle.

Then closing a front door fully opened in a sit down state, a switch is manipulated to the closing side. Then, the closing manipulation of the switch 42 is detected (S10) and a second limit switch is judged whether it is switched on or not (S11). In this time, since the front door is positioned in the closing motion zone from the fully opened position to the middle position, the turning-on actuation of the second limit switch is detected and the driving motor is driven reversely (S12). After a waiting time until a specified delaying time DT elapses (S13), an electromagnetic clutch is turned on to drive the front door to the closing direction (S14). When the front door reaches the middle position and the second limit switch is turned off (S16), the driving motor stops (S17) and the electromagnetic clutch is turned off (S18) and then, the motion of the front door to the closing direction is stopped.
