PROBLEM TO BE SOLVED: To improve the quality of inspection by properly determining the presence of electrolyte leakage. SOLUTION: This electrolyte leakage inspection device has an irradiation means 1 for irradiating light, which reacts to an electrolyte 51, onto battery 50, a photographing means 2 for photographing the battery 50, and a determination means 22 for detecting fluorescence emitted from the electrolyte 51 by the reaction with the light from the irradiation means 1, by the use of an image photographed with the photographing means 2, to determine the presence of the electrolyte leakage from the detection result.
