PROBLEM TO BE SOLVED: To provide a filled-state measuring apparatus in which an antenna does not transmit microwaves in the region of a measuring-apparatus fixation part, in which the antenna does not receive reflected microwaves in the region of the measuring-apparatus fixation part and which is operated by the microwaves. SOLUTION: A filled-state measuring apparatus which is operated by microwaves and which is fixed to a container 3 is provided with a casing 11 and with a rod-shape antenna 7 which is fixed to the casing 11. Then, the antenna 7 is directed in the direction of the container 3, it is composed of a dielectric such as, e.g. polytetrafluoroethylene (PTFE) or polyphenylene sulfide (PPS), and the part adjacent to the casing 3 of the antenna 7 is surrounded by a metal sleeve 8. |
