Abstract: A battery can hole detecting apparatus detects whether or not battery cans formed by a drawing operation are defective and leak because a can has a hole. Battery cans which are continuously fed in are placed on the outer surface of a rotor and thereby carried to a first or second discharge port. During this movement, air is introduced into the inner space of such battery can to detect whether or not the battery can is leaking according to whether or not the pressure of the introduced air reaches a predetermined value. Battery cans which are not defective are discharged at a first discharge port, while battery cans which are defective are discharged at a second discharge port.
