PROBLEM TO BE SOLVED: To provide a stroboscope by which strong emitted light is obtained at low voltage. SOLUTION: A high current to such an extent that it ordinarily ruptures an organic EL panel 5 for one second or less is instantaneously made to flow to the panel 5, so that light is strongly emitted only for a very short time and irradiates a subject. Since the high current is made to flow just by directly applying voltage outputted from a DC voltage source 8 such as a battery to the panel 5, a step-up transformer required when using a xenon lamp requiring several kV is dispensed with.
