PROBLEM TO BE SOLVED: To perform a positive and rapid detection of a defective can when an inappropriate sterilization of a vacant can Ec under atomization of medical liquid occurs. SOLUTION: A method for detecting an inappropriately sterilized can is carried out at a sterilization step for a vacant can Ec where sterilization liquid adhered to the vacant can Ec is decomposed and removed by atomizing sterilization liquid while the vacant can Ec is being rotated and by blowing hot air against the vacant can Ec having the sterilization liquid adhered to it, wherein rotating states of suction pads 28 sucking and holding the moving vacant cans Ec are detected in sequence for every can Ec with a plurality of sensors PH1, PH2, PH3 and PH4 arranged at predetermined positions at the midway part of a transferring path, and when all the detecting signals of each of the sensors PH1, PH2, PH3 and PH4 are light shielding states or incident light states, it is judged that the vacant cans Ec sucked by the suction pads 28 are inappropriately sterilized.
