Abstract
A leakage detector of endoscopes inspects cracks and pinholes within an endoscope of the perfect watertight structure by detecting leaked air therefrom while applying compressed air in the endoscope and, when no defect such as cracks and pinholes exists, controls by means of a relief valve so that the rise of air pressure within the endoscope assumes a given value.
