Abstract: The present invention provides a strobe device which includes: a light-emitting unit rotatably coupled to a strobe body unit which is detachably mounted on an imaging apparatus; a variable mechanism capable of varying an angle of orientation of the light-emitting unit with respect to the strobe body unit; a driving unit for driving the variable mechanism; a control section for controlling the driving unit; and a detection unit. The detection unit detects that the strobe body unit is detached from the imaging apparatus, and the control section has a mode of varying the angle of orientation of the light-emitting unit to a predetermined detached-state angle of orientation based on a detection result by the detection unit. With such a configuration, it is possible to realize the strobe device which can obviate an unnecessary operation by a user.
