To reliably allow a capacitor of an electronic device to discharge when the device is shocked.
The electronic device includes: the capacitor unit which accumulates charge supplied from a power supply in space between a pair of electrodes and supplies power to a load by discharge; a shock detection unit which generates an electrical signal while power is not supplied from the power supply when shock exceeding a given threshold is given; and a discharge unit which short-circuits the pair of electrodes while the power is not supplied from the power supply when the electrical signal is received. A light source for continuous light may be supported in a housing to be arranged in a direction where continuous light illuminates a lower side of the housing when a light source for flash light faces to an object to be illuminated.
