Abstract

To provide a leakage detecting device capable of detecting leakage with a high degree of accuracy. Pulsed laser light L is condensed with a reductive condensing optical system 51, fairing it to a circular geometry correspondent to the geometry of a negative electrode face 23 the leakage of lithium electrolysis solution of a lithium coin cell 2 is to be worried. The pulsed laser light L condensed to a circular geometry is irradiated to the central portion of negative electrode face 23 of the lithium coin cell 2. Leakage of lithium electrolysis solution from a lithium coin cell 2 is detectable with a high degree of accuracy, even if fluorescence F generated from emission by irradiation of pulsed laser light L might as well be determined from quantification with a discriminating device 67 after spectral analysis with a fluorescence spectrometer 65.
