To realize miniaturization and the reduction of the cost by reducing operation stages and further reducing the number of parts such as a lead wire in the case of disposing a plurality of xenon tubes on a base plate.

In this stroboscopic device where two xenon tubes 1a and 1b having an anode and a cathode respectively are connected in series, the xenon tubes 1a and 1b are connected in series by respectively folding only the anode or the cathode and directly soldering the terminal parts of either one each other.
