- the open end of the conductor 14 and the spindle 36 are arranged so as not to be substantially capacitively coupled (or have a capacity much smaller than the capacity formed between the open end of the second conductor 16 and the spindle 36).
- the RFID tag 10 can be made compact, the frequency characteristics can be stabilized and the communication distance can be increased, and therefore the high frequency transmission characteristics can be enhanced. Further, since the RFID tag 10 in which the first conductor 14 and the second conductor 16 are arranged in a spiral shape need only be arranged in the vicinity of the spindle 36 (that is, work such as processing of the handle 34 is not required, and the valve And because the container itself does not need to be processed), the cost can be reduced. Further, since the depth can be arranged on the inner wall of the handle 34 having a size less than ⁇ / 2, the reliability of the tag can be greatly improved as compared with the case where the tag is attached outside the valve or cylinder.
