The invention relates to a both-end sealed type short arc flash lamp, a lamp holder can be fixedly fixed to a sealed tube, outside leads of starting auxiliary electrodes in the lamp holder are not conducted, so that stable lighting can be realized. A pair of main electrodes and starting auxiliary electrodes are arranged in a luminescent tube, in a first sealed tube of the luminescent tube, a core wire of a first main electrode is sealed and derived out of the luminescent tube, a glass tube for seal is welded to a second sealed tube, in the glass tube for seal, a core wire of a second main electrodeis sealed and derived out of the luminescent tube; the lamp holder is fixed to the second sealed tube, Young modulus (Pa) of a first adhesive fills in a gap between the internal lamp holder and the second sealed tube, and at least resistivity (Q.m) of a second adhesive fills in a gap of the internal lamp holder and the sealed glass tube; an external lead of the above starting auxiliary electrodes is embeded into the above second adhesive and is derived to the outside. |
