A water tank 11 is provided above 0. Above the water tank 11, a fixing jig 13 for mounting an object to be inspected 18 such as a faucet fitting is arranged, and is formed so as to be movable up and down by a cylinder 12 provided on the pedestal 10. Above the fixing jig 13, a video camera 14 for photographing bubbles ejected from the object 18 to be inspected.
And a lighting device 17.

理制御部15に送出する。In the leak tester of the present invention, the object to be inspected 18 to be inspected is attached to the fixing jig 13 in a state where the fixing jig 13 is located above the water tank 11. By the cylinder 12, the fixing jig 13 is moved downward, and the inspection object 18 is submerged in the water tank 11. Compressed air is introduced into the device under test 18 by a device (not shown). Bubbles ejected from the object to be inspected 18 are photographed by the video camera 14 while being illuminated by the illumination device 17, and the image information thereof is sent to the processing control unit 15.
