Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power source circuit of an electronic device which makes it possible to prevent effectively life degradation of a battery accompanying a rapid fluctuation of a load. SOLUTION: The power source circuit 15 is equipped with a DC/DC converter 151 which converts an output voltage of a cell 5 into a voltage for which each of a stroboscope control circuit 14, a drive circuit 7, and a system controller 12 asks. Electric double layer capacitors 152 for preventing the life degradation of the cell 5 from being caused by the rapid fluctuation having generated by rapid stroboscope control circuit 14 and the drive circuit 7, etc., are equipped in a secondary side of the DC/DC converter 151, intervening between the stroboscope control circuit 14, the drive circuit 7 and the DC/DC converter 151, that is, without connecting directly with the cell 5 and the electric double layer capacitor 152, in order also to prevent a leak which the electric double layer capacitor 152 generates at the time of power source OFF from having adverse effect on the cell 5.
