Abstract

PURPOSE:To improve certainly and response and to perform leak inspection without being affected by the kind of a body to be inspected by allowing to detect pressure variation as dynamic and static variation of a floating body by a photosensor. CONSTITUTION:When internal pressure drops owing to a defect in the airtightness of the body to be inspected, pressure applied to the liquid surface in a liquid chamber 31 drops, and the pressure of the upstream-side compressed gas at a leak check part 21 rises; when the floating sphere 33 is floated in the liquid at its upper part by compressed gas blown as air bubbles out of the opening 32c of a nozzle 32, the optical sensor consisting of a projector 36A and a photodetector 36B through a transparent liquid storage container 28 detects the floating sphere 33 to detect a defect in the airtightness of the body to be inspected. Consequently, the certainty and response at the time of the leak inspection are improved and the kind of the body to be inspected is made irrelevant.
