Claim 15:
16. A locking/unlocking device comprising:
a drive unit, including at least one of an actuator and a motor as a drive source, configured to drive a lock mechanism of an opening/closing device;
a magnetic detection sensor configured to detect a change in a magnetic field based on a change in a relative position between a movable section and a fixed section of the open/closing device;
control circuitry configured to determine an open/closed state of the opening/closing device on the basis of the change in the magnetic field detected by the magnetic detection sensor, and to activate the drive unit to lock or unlock the lock mechanism on the basis of the open/closed state; and
a housing that accommodates the drive unit, the magnetic detection sensor, and the control circuitry, wherein
the lock mechanism includes a thumb turn,
the drive unit further includes a thumb turn holder that holds the thumb turn,
the drive source of the drive unit rotates the thumb turn holder, and
in the housing, the magnetic detection sensor is provided on a side opposite to the drive source with respect to a rotation center axis of the thumb turn holder.
