PROBLEM TO BE SOLVED: To provide an anti-theft tag capable of detecting the consumption of an incorporated battery precisely. SOLUTION: Two small and circular recessed parts 5 are formed between the sensor button 22 of a the box member 2 of a front surface side and a cover member 4, and external contact terminals 14 electrically connected with a battery incorporated in a casing 1 are respectively fitted into both of the parts 5. When the casing 1 is not fitted to an object, a probe connected to a detector such as a voltmeter is abutted on the terminals 14 to detect voltage to discriminate the consuming degree of the battery 12 precisely. When the casing 1 is fitted to the object, the openings of the parts 5 are covered by the object. Thus, it becomes impossible to operate the terminals 14 from outside. |
