Abstract
A conventional apparatus for preventing growth of microbia in a carrier tube by an electromagnetic field has no or little effect. An apparatus 1 serves to prevent growth of microbia propagating themselves on an internal wall of a carrier tube 63 for carrying beer and the like or to remove the microbia. The apparatus 1 comprises a control unit 2 for generating an electric signal including an audio frequency component, a transponder 3 including a coil 31 and a case 32 for housing the coil 31, and means for attaching the transponder 3 to an external wall of the carrier tube 63, and generates an audio electronic signal to be sent through the carrier tube 63 by applying the electric signal to the coil 31.
